kay333, I so feel for you. I was about your age when I started getting depressed. It was mostly because I hated school so badly. I'm now 33 and just started having real bad anxiety about 2 months ago. I'm lightheaded constantly, sweaty, you name it, I have been through the symptom. I completely understand what you mean by feeling sick and alone. I feel the same way. I don't know how long you have been going through this but in the 2 months I have been dealing with it, I am finding it somewhat easier to deal with. I mean everyday I still have really scary thoughts. I have been trying different medicines and have finally found one that hasn't given me really bad side effects. I'm hoping it will kick in and help me. Have you talked to anyone about this? If not, please do so, it does help ease things somewhat.
