I would start with lowering your dose of Prozac. Have you ever tried just a mood stabiliser and antipsychotic? Maybe then (if you still want off all meds or smaller doses) the lamotrigine and then the Risperdal. Maybe increasing the doses of the other meds while gradually lowering the others.

If you really feel smaller doses is the best way to go and they won't relent, just do it. Very gradually, one by one.

Edit:
Anxiolytics really don't work in the long run. They only treat symptoms (which might be helpful/necessary in some more extreme situations), don't do much more, lose efficacy and are difficult to stop taking, having mainly paradoxical effects even when still on them. It's mostly paradoxically bad in nature. A real spawn of Satan. Alluring but soul-crushing.

Any (typical; not incidentally extreme and really longterm life-threatening) depression is better fought without them. Better to have yourself completely harmlessly sedated than to use them.

I just had a friend thinking about going inpatient because he already was on an antidepressant longterm. In other words, it limits your options when you need help most.

Another edit:
But a spawn of Satan is sometimes just what you might .
Just saying, so you don't think I am just yet another one who tells you to use this or that or any med—ever. None of us (as far I know) says that.
