You would probably benefit greatly with an anti-depressant. I honestly believe Prozac saved my life. I couldn't function for crying. Yes, I have been taking it for years now, but my dosage doesn't have to increase. It still works, but it doesn't totally numb me down, which I wouldn't want anyway. I remember the first time I tried it, I didn't take it long at all because I couldn't sleep. Later when things got worse, I tried again successfully. Just give it time. It doesn't make a difference over night.
I suggest you see a doctor. If one med doesn't work well for you, try another. Many are opposed, I'm sure, but there is a time and a place for appropriate medication. Good luck.
