Hi, Wdr3.
I am not diagnosed with autism or Aspergers.
I can relate well to certain points here.
I know mimicry and the chameleon complex all to well.
Actually, I exhibit pretty much everything you described. I however, do not have tics. I have stims. I also have a great imagination and am artistically and musically gifted. I don't read because it is not stimulating enough to keep me sitting in one spot.
Are you nearing the end/and or have been done with high school now? That is when people suffering from the social problems of Aspergers/autism have a prominent decrease in there social lives.
