Psychotropic Drug question

Ok, so this is my first post here, so I want to make it a good one :) I have been diagnosed with a lot of things over my lifetime, and the latest one happens to be asperger's syndrome. The question has to do with the way the doctors have treated it in the past and present. I have been on countless medications since I was only 9 or 10 years old (before I was diagnosed with Aspergers). none of these seemed to have done any good. To get my point across, I have been writing my feelings, etc. in a journal. Here is an excerpt:

    When I was 10 years old, I was diagnosed 'ADHD,' at

which point I was started on Cylert, which I stayed on until I was

13. This is when I was put on Strattera due to severe depression

problems, which we thought MIGHT have been due to the Cylert.

Two years later, I was put on Prozac, due to steadily worsening
symptoms of depression and paranoia. At this point my memory becomes
muddled, probably because I was also put on a medicine called Wellbutrin,
and things went downhill from there. I became dependant on the medication
for sleep, and began experiencing 'ticks', some of which were plainly
visible to others. This caused the doctors to switch me over to different
drugs--rispridal and serequil-- on top of the Prozac. These also caused me
to become highly dependant for on them for sleep, and I slept most
of my days away after I graduated from high school. This is when I decided
to begin 'experimenting' with the medications, taking myself off of them
or missing dosages. At this point I started to sleep during the days,
and stay awake all night; or worse, not sleep at all for days at a
time. I am currently taking Prozac, Abilify, Clonazpam, and Propranalol.
I am not skipping doses or anything, yet I still feel "held back" by a
general slowness in my mind.

is this general slowness caused by the meds? if so, which one is causing it? Should I even be on these medications?
thanks in advance
