Here's my story.

So lately I just can't do anything I enjoy anymore. I got really excited about a PS Vita (game) but now the somewhat thought of it makes me feel nauseas for some reason. I obsess so much over stuff that eventually the thought of it makes me feel sickly and such- then I worry. Right now my stomach just gurgled and that makes me nervous (I'm severly emetephobic). But I'm in school all day, and I can't look up cool stuff then because obviously the teachers will yell at me and get mad. So I get home and have like no time to enjoy stuff I'd like to do because I start feeling crappier and crappier as bedtime nears. Like my tonsils swell up and they hurt and it becomes hard to talk, sometimes I feel weak, but I like going to bed hungry because it makes me feel like I can't get sick then. I'm just tired though because all the things I used to enjoy I can't do becasue I worry about them too much. I don't know what to do anymore. Help me...
Thanks.

not being interested in things you used to enjoy is a sign of depression. check it out.

You also sound as if you have some unresolved anxiety issues occuring.

A lot of your physical symptoms could be due to the anxiety.

Do you have someone who can help you through this phase that you can talk to that you trust?
