as a mother of a daughter with autism, i can only say to be there for her. she will come around. that first year is the hardest, as everyone says that early intervention is the key, and the parents are left wondering if they're doing enough. so bring her dinner (don't ask, she won't say yes), even if it's just a pizza, offer to pick her up some things at the store, offer to go to dr appt's with her, write her a note or an email or a text message that just says you are thinking about her. understand that you can't understand what she's going through. sounds to me like she just wants to prove to herself that she CAN do this. once she's come to that realization, she'll start asking for help. it takes awhile though.
