I've not read all your responses, but I know a little of how you are feeling. This is a VERY interesting article about anti depressants

I've been where you are and took Paxil for 18 months. Actually the reason I stopped (finally) was that I learned that Paxil is associated with a seven fold increased risk of breast cancer. As I already have a strong family history, I got off it immediately I read the about it.
What I did to replace Paxil was start to exercising. At age 48 I decided to get off my butt and get moving, because I'd heard that exercise helps with depression and anxiety. (I suffer anxiety more than depression). I am religious about exercising - and I've found it better than medication. I did find it really difficult to get off Paxil. It took two weeks of flu like symtoms along with the sensation of a power station inside my head. I was also edgy and vulnerable for a while after stopping it. However I was VERY determined to get off it. I was also very determined to exercise. I started swimming and walking. I swim 1.5ks every second day and walk on the alternate day. This involves 35 to 40 minutes of excercise a day - but the effects are fantastic. As a bonus I'v slimmed right down and I am now a much better shape than I was. My motive wasn't to look good, rather it was to feel good, but looking good has been a added bonus.
Exercise is not a cure-all. But nor is medication. Sometimes we have to accept that we have vulnerable aspects of our personality. I don't think we should try to change ourselves too much, rather we should be kind to ourselves and accept our selves the way we are. Make sure your diet is as healthy as possible and especially rich in Vit B. (Brewers Yeast tablets are excellent for the nerves).
Before I get off my soap box I will tell you that I've met a lot of people at the pool who swim for mental health. One lovely lady aged around 55 has been going every day for six years. She nursed her 29 year old son until his death from leukemia and the depression that followed her loss was so overwhelming she thought she would not be able to carry on living. Her doctor recommended swimming and it helped her to such a degree that she doesn't ever want to stop. You don't have to be that good at it - she just paddles up and down the pool for half an hour every day. Every time I see her I think of the tragedy in her life. I find her an inspiration!
All the best
