i don't know what to do

this morning when i was still in bed, i called the office and asked tyan when i was going to get up and she said, "7:30" and 7:30 rolled around and i still wasn't up, so i called the office and she claims she said 7:30 or so and i told her that my mom was coming and i wanted to be up and finished walking with my walker and she screams into the phone, "STACY, I DON'T CARE ABOUT YOUR MOM OR GRANDMA, I'LL GET THERE WHEN I'M READY." and i just laid the phone down on my bed as she screamed all of that, so that i wouldn't yell anything back at her, she then said, "stacy? are you there?" because she expected me to say something and i didn't, so she hung up the phone. i called my grandma after she hung up the phone on me and she told me to just act pleasant. after i got off the phone with her, i called maurice and he gave me the advice to call robin and leave a message on her answering machine, so i called robin and said that i thought tyan shouldn't be talking to me like that and i wanted to be all ready for my mom when she picked me up. when i just got in the office, i think that robin just said that i liked to spend a lot of time on my walker and my mom was coming to take me to her house, so she should've just got me up this morning without saying anything. i told my mom that she said that and she told me that i shouldn't have to put up with all of this that has been happening to me and she i think that she wants me to move and live at home. i want to get my strength back and right now, i'm able to walk with my walker (to help me gain strength to walk) and do more for myself but i think that i definitely need to move but i don't know of any good places and i don't want to live in a foster home again and i don't really wanna leave maurice because i know that as soon as i move, they'll put him in a nursing home and he'll be lonely. *takes deep breath* i don't know what to do. i know there's better places. i hate having to depend on people for things.
