do i need to slow down?

i'm at gillette for physical therapy for my neck. i was driving my wheelchair and following my physical therapist back to the therapy gym and then *BAM* and my reaction was just screaming, "OH FUCK" after i hit the wall. i guess that i fell asleep while driving my wheelchair and drove right into the wall. the sad thing is that i'm not kidding. my physical therapist slowed down and said, "whoa! i better watch out, you're gonna run me over next!" i was feeling a little tired during my physical therapy session but i didn't expect to fall asleep. i still have to do homework for my classes tommorow. shit. i don't know if it's the meds or if i might be doing too much and i might need to slow down? i don't know. i just don't want to get so overwhelmed that i have another seizure. either that or i need to start taking my ritalin sooner. this epilepsy is just kickin my ass.. making me fall asleep while i'm driving my wheelchair and making me run into a damn wall. shit. i still won't ever forget when i seen a lady (who was epileptic and lived in my previous apartment in minneapolis) walk into an elevator (as it was closing) because she fell asleep, after she walked into the elevator, she just rubbed her head and got up like it was nothing- or an everyday occurence. i felt like crying when i seen her walk into the elevator and get up like nothing happened, when people who seen it happen were concerned. it's sad that i think that i've actually got that bad. there's this epilepsy foundation rally flyer which i recieved in the mail today but the tickets are $90 per person and i don't think that i have that kinda money.
