HEY, I have (almost) exactly the same problem! I have just started at a new school for various reasons
and yeah, everyone thinks I am lonely just because I sit alone, at least, try to. People keep coming up to me, and I have to fix a smile and talk about stuff. Blaaah. Sooo glad this is my last year at school...and all the teachers are worried about me, and talk to parents etc!
Yep, I dread lunch time - at least, when I have to talk to people who feel sorry for me ( grrr, don't don't!). Try going to the library, behind a shelf and read Guinness World Records or something completely unrelated to school work. Lunch time should not be study time, or social time( for the "uncertain" aspies)...he he
