Despite how optimistic I say I am, I've had this kinda' problem before, Syra. At one point, in seventh grade (before I even came out as Furry) one of my best friends ignored me almost completely in favor of a new one. I looked at what I thought he thought of me: I thought he thought that I was extremely annoying and I should just go away. I became blind to the fact that it was only him that seemed like this, and that all of my other friends still loved me plenty. After a week, I realized this and biting down my pride, I stopped hanging out with him.
So: Get proper sleep and eats and such, and don't let your ideas of a select few break your opinions on others. Because, like me and FireWind, many, many people love you for who you are.
And here's a saying: If you don't think you can do it, then you can't. Meaning, you have to get yourself to believe in yourself, otherwise you're breaking yourself thinking about "what ifs" and such.
The LAST thing you want to do for sure is break connections based on your current mood. Nothing good will ever come out of doing so. And, yes, this has a point to it. In the case of depression, people can lose their lives or parts of themselves, and I won't have that happening with someone as lovable as you!
