Bullying is truly a terrible thing, the good news you generally won't find that at uni and if you do, it's no longer "kids being kids", people at uni are adults, bullying is assault and if anyone bullies you you can literally go to the police for that and they won't just get a slap on the wrist. So I'll talk about going into uni and so forth later, but the first thing I should stress is to take your medication if you feel you can't cope. A lot of people with psychological disorders go off their medication because they think they can and a lot of people (with depressive disorder or bipolar disorder especially) end up hurting themselves, or putting themselves in a position where they could hurt themselves. No way am I saying that's you, but it's important to take your medication if you feel you need to and there's absolutely no shame in that, after all it sounds like this anxiety wasn't really your fault in any way, more the situation that you had been placed in.
So uni, now uni is different for many people. Taking a gateway course is good, generally there are many avenues to get into uni so try them all. In general, universities generally have a disability program that can help with stuff and also help with applying (getting a "leg up" to try because you were sick). Your anxiety, IBS and visual problems could most definitely count as a disability so it's important to try to seek these avenues within university to try and get on the same level field as everyone else. Now, university and college can either be the best experience of your life and a generally terrible one and how the experience comes to be is defined on what you do. If you are going to university just to go to classes, learn and get a degree, then you're not gonna have a good time at uni. University allows for a thriving social life, you'll make more friends (that are much more mature than your high school friends), you'll be able to unleash your potential in more open ended avenues and extra-curricular activities, or even just asking the lecturer for more problems (they usually are glad to give them) and you'll be able to share experiences with like-minded people (such as those of the LGBT society, which is almost definitely somewhere on your uni). In general, the university experience is exactly that, an experience, and you should try push for the experience part just as much as the academic side of things (after all these extra curricular stuff would look fantastic on your resume
). Now, it depends what degree you're doing, if you want to do a degree in Engineering or computer science you'll generally find everyone there is kind-of-sort-of nervous, shy and well, I suppose slightly autistic xD, so in general you won't have the Jocks of high school trying to make fun of everyone (Do note however, this won't be all the people, a majority of people in these fields are actually quite outgoing and friends, but if you prefer the quieter type there are those around too). If you pick something like sport-science or civil engineering, you'll generally get more "jokish" people. Law and social sciences are generally full of people who are quite political in nature and very interested in the concepts of politics, rights and so forth. Sciences differ on the field, generally physicists are basically like the compsci people but have even worse social skills I find, chemists and biologists seem to be ok though. The point is, you'll get different people depending on your subject, so in general if you liked one subject you'll get people who are similar to you in that regard.
My lecturer Richard Buckland was a godsend for nervous and anxious people like you, he was my first year computer science lecturer and is widely considered the best lecturer to be a student for (and the worst lecturer to be a tutor for
). One thing he said, which is undoubtably hard for someone with anxiety but is really helpful if you can at least try this once or twice, is to sit in a new seat every day for the first two weeks, a seat you hadn't sat on before. Then say hi to the person on your left and the person on your right, just say hi, it's not weird or anything in the first two weeks, you'll meet new people, you'll see them around and in general, people will be friendly. You have a clean slate! So use it!
Now enough about Uni, lets talk about sexuality. First of all Alan Turing isn't the only "last" famous British homosexual guy, but he's probably the most influential. Either way, there's an entire list on wikipedia of famous LGBT people that's so large, you have to search by letter, it's found here:
http://en.wikipedia.org/wiki/List_of_gay,_lesbian_or_bisexual_people:_A Many of these entries are British. Now I could say that there's nothing to be concerned about and homosexuality is normal and yadadada, but I'm sure you've heard that before online and you in general already know that. I dunno, for me these words didn't really help, maybe they lifted my spirits for a night but then a few nights later I'd be sad again. So what helped me get over, I suppose, the grief that *GASP* I'm gay. Well, for me it was the people I hang out with. Now, some people like to feel proud to be gay and they like the whole world to know, to those people I say awesome, if that makes you happy than do it! Fly the rainbow flag with pride and show the world that you're proud, but I wasn't one of those people. For me, I didn't LIKE the idea of being proud or making a big deal out of my sexuality, whether it was negative OR positive. I wanted it to simply, not be a big deal, a part of me that was simply "meh", a part that was only important in my romantic life, but unimportant in my daily life. So, I tried to find a community that would accept me for who I am, without making a huge deal out of it, and well I found that community in this forum and in the furry fandom itself. Because, surprise surprise, a majority of people are aren't straight, just check out the "sexuality" thread in the General section, most people are Bi, some are gay, some are PAN and some are asexual. So no one really cares if your gay and that to me gave me some confidence with coming out about my sexuality, which you've already done so well done! But I found out something very curious, I found out that in general, with things like this, people will only consider something a big deal if YOU consider it a big deal. If you consider it a small deal, then people in general will also, there are obvious exceptions to this, but if the people you are talking to are generally intelligent (like the people in university) then you'll find this to be true more so than false. Either way, I followed that principle, and in general acted like being gay wasn't a big deal, I wouldn't tell people I'm gay unless my romantic life came up in conversation, and then I'd just say something like "Do I have a girlfriend? Nah, I have a boyfriend, his name is Lyle, what about you?" and in general if I didn't attract too much attention from it and in general was "relaxed" people would reply the same.
That was my experience, your experience will be different, but I think it's important to find a community that'll accept you in the bounds that you would want to be accepted in. If you are a rainbow flag baring type, which many people are, then you should check out the Queer society of your college, who'll gladly accept you and encourage to you participate in activities that will strengthen your resolve for your fellow LGBT peers!
