How old are you?
You gotta remember that when your younger your sort of ignorant to the horrible things people can, and will do. Also, when you enter late teens (16 onwards) you'll become more socially anxious, because that is when peoples opinions start to matter.
You could go down the road of about 80% of the people on this site, and dont get a girlfriend, dont get friends, think everyone is evil and cry all the time. OR!
You can do what people have been doing for millions of years and stop thinking about it, and use the anxiety to fuel you instead of getting more and more socially withdrawn, until you start to blame everyone else for your faults.
Just sit down and think. Think about all the good things that have happened to you and all the good things that will happen to you again. If you go out and meet people with a negative attitude, you might as well but a bag on your head. Because at the end of the day, nothing about you has changed. The only things that have changed are in your head. And unless your smoking loads of weed or spending to much time inside you dont have to worry.
Just get out there. The more time you spend in these situations that make you feel uncomfortable the better you will get at handling them.
Also, in my experience, dont talk about your problems. Because 90% of the time your problems dont seem as bad if you just stop talking about them all the time.
Now i dont know how much of this will be relevant to you.. Because obviously, i have no idea who you are!
But.. If your anything like i used to be then some of that might help.
Just remember, everyone has bad times.
Loads of homo-erotic love.
