I was on SSRI's 15 years. Also, quetiapine for about 10. Didn't make me better. Made me worse. At the peak of the decline, I was 3 years on medical leave and have just been institutionalized for demolishing my room in a fit of rage. In the hospital, me and everyone else there were treated like shit.
After that, I quit every medication, tapering off through a long period of time (about 4 months I think), except the benzos, which I take from time to time before bed, cause the other meds gave me severe insomnia. Once I quit the drugs, I couldn't sleep anymore.
Anyway, I'm not suggesting anything. If you are motivated to get help this way, do it. Quetiapine, at the beggining, for years, was really working for me. Helped with anxiety, an it was pretty evident in my case, cause my tremor subsided considerably.
In the long term though, I'm not so sure drugs are the answer. Brain chemistry is not something to be messed with lightly.
I've been almost 3 years off. I can't say I'm better, I can't sleep and my dark thoughts are here, but at least I'm still working, I'm functioning and my job is not on the line because of meds (it's a long story, which I won't go into now). I don't have severe outburst anymore and not once have I smashed anything in all this time.
Despite my core problem, I call this being a little bit better.
