Please see a PDoc if you have not already. Your symptoms sound a lot like mine.

I have Major Depression with psychotic features and am treated with anti-depressants plus a strong anti-psychotic. Those meds allow me to work a full time job and also keep me from killing myself.........blunt, but true. (Sometimes I hate that fact! But when I begin to think about suicide again that is my prompt to head back to the doctor )

The symptom I hate the most is the distorted thinking!

Please take care of your self and don't hesitate to get a second opinion.
