Sorry if I come off as kinda umm we'll say cranky since there are children here, and I have to keep my language in check. BUT, oh dear god hun it will pass. You're only 16, pay attention to your life and make sure things go smoothly for you. Yea it's going to hurt, it's probably going to hurt a lot. And it wont seem like there's an end, but it does. There's this thing called college, YEA! Or even getting out on your own.
Now I haven't dated many people, total of 3 I think. So I'm no expert, but don't fully commit yourself till your ready. I read so many things on these forums of people being in love when they are so young, then getting hurt. I want so much to scream at them, to just tell people to enjoy what child hood you have. You have the rest of your life to grow up, and be an adult. Don't waste what fun care free years you have on someone who's not going to treat you like you deserve to be treated. If this person you calmed you loved can tell you out right they hate you, then they were not the one. If that's the case do what you must to get it out of your system, then get over it and move on.
Just because something in your life mucks up doesn't mean life stops. I should know, my life is a jumble of crap, that I try to sort out every day and I'm 26!
But you should make your own mistakes, and learn from them. Life is not easy, and gets harder as you go. But if you can't deal with the little things, there is not much hope for the future.
Take my response how ever you wish, not trying to be mean. Been in that situation, know the feeling, and have had worse done to me. So I have an idea of how you feel.
