Effecting my life at only 18 years old?

That sounds pretty serious. If I were you, I'd go to a counselor/psychologist. Most of the physical symptoms you are experiencing can be related to anxiety. I think you would benefit from Cognitive Behavioural Therapy (CBT): a href="http://www.anxietynetwork.com/hcbt.html" rel="nofollow"http://www.anxietynetwork.com/hcbt.html/a A psychologist could give you this therapy. It has very high succes rates and is often used for anxiety. Sometimes it is temporarily combined with meds, but with CBT you'll be able to function without meds eventually.
