Rather than seeking help with a pill pushing doctor who really doesn't understand mental health, and gives out drugs that aren't proven beneficial long term, I would highly recommend attacking the problem rather than the symptoms. Sure popping some pills may take some of the negative feelings away (temporarily), but until you get to the root of it and make some self realiztions, you are always going to be plagued by it. Seritonin has never even been proven to be the cause of anxiety, and similar disorders. It plays a factor obviously, but isn't necessarily the problem. You know that we don't even know really how wellbutrin acts on the nervous system, and its method of action? To take something like that is a little crazy. (this is current to my knowledge...I haven't looked into it for a while)
Man, I've been there before. Been on paxil, celexa, effexor, buspar, ativan, xanax, and valium at one point or another. Somtimes I felt better, but they all had side effects, and as soon as I quit taking them I realized that not only were the problems still there, but I had been dulling my sense of self awareness, and it was most often worse when I quit (formation of dependance).
I would recommend talking to the doctor for a regular checkup and some bloodwork (low thyroid levels can effect you in that way), but before you start popping pills that very likely have some long term side effects, try the inositol/sam-e route, and talk to the Psychotherapist. NOT a counseler, not a psychologist, not a psychiatrist (although many psychotherapists are doctors, licensed shrinks...ect as well). Until I did that, and realized some things about myself, I was all screwed up mentally (taking a cocktail of doctor and Psychiatrist prescribed pills didn't help).
Another recommendation, read a couple books about SSRI's and like drugs. The one that made me realize I was going about the problem all wrong was "Toxic Psychiatry" by doctor Peter Breggins. You'd be surprised that many of the drugs available on the market were only tested for a period of weeks, on less than 200 subjects before being released to the public. And, during these tests, some were shown to make problems worse in the long run (why they released them anyway is beyond me).
In any case, I wish you the best of luck as I've been there and know what your going through. Stay strong, take chances, and you'll realize you got a lot more going for you than is readily apparent. Really, really research these drugs before you take any of them. Medline is a good place to start, as you need non-biased info that is hard to come by with the pharm companies dumping billions fo dollars into thier marketing.
