gsmax5, yes. my brother's friend got me a job once. after i quit, my brother told me his friend said everyone there thought i was slow. he meant it in all seriousness, wasn't joking.
i get "she must be retarded"/pity vibes from coworkers and other people i interact with all the time. basically i AM scared shitless to be there but i HAVE to be there- i have no choice. i have to work. i am so socially inept and just barely cope. it is all very plain to see and quite humiliating.
i can look normal from afar, if i'm just walking around in the grocery store or something. once you start talking to me beyond, "hi, how are you," it's obvious my social skills are handicapped. i can never get far past that point- this is when my terrible awkwardness becomes apparent.
