Oh gosh, yours sounds very similar to mine! I started on escitalopram, which really worked wonders for me initially. Totally took any bit of anxiety away from me. But I eventually fell flat on it, and some of the side effects sucked. I then went to venlafaxine, which was kinda meh for me. Less side effects initially, then I ended up being on a very high dose due to my health being crap, then ended up with a tonne of unwanted side effects. Came off it, and boy was that a ride. It made me feel really sick
now I'm on sertraline. It seems to be okay for the most part, but still not as good as when I first started on anti-depressants. I'm not sure if I'll ever find one that works well for me either!
