It might be a good idea to get a second opinion from a psychaitrist, don't know if a p-doc is the best at knowing what's best for someones mental illness. Though psychiatrists can be kinda pushy about meds to so not sure that would really make much difference...maybe worth a try though.

If the zoloft isn't helping and making you feel worse you can stop taking it even if the doctor advises against it, they should at least guide you in quitting safely though...I mean sure its good to follow treatment plan but in the end it's your body/mind not theirs and if you know its detrimental than you have to do what you need to do. I guess I get sick of the notion people should just do as directed regardless of what it is doing to them.
