I Am Running Away

It started last week and I was thrown out of my house by my mother who has tried to make me not leave before. Previously I've packed my things and left because she has inflicted damage and harm on me in the past and kicked my siblings out so I know she's not that concerned. She hasn't tried to contact me but now I'm staying with a friend. This co-worker of mine first off I didn't exactly click with, she can be controlling and kind of intrusive. Maybe I'm not used to it because she isn't a parent but middle-aged so she has never been separated from a son or daughter but her age apparently makes her opinion better than mine, even though she hasn't gone through what I'm going through. I appreciate her help but she doesn't let me go back to get any of my things. She wanted me to go buy clothes and things I didn't want and I could've gotten more things at a time when I know my mom will be out of the house. This friend is also someone who has cut off her family, and even though I haven't shared the whole story with her, she is insistent on getting me away but I don't have a chance to take much with me. Instead she waits on her boyfriend who doesn't work and they play video games. I've been planning a move to Minneapolis since winter and I was going to go this spring and stay with a cousin of mine, and start with a new job. I really only spent time with her recently and she's close with my mom but I think she'll be tight-lipped. I've been accepted to college in the fall, and I'm really only staying with my co-worker to cut costs. We don't have a good rapport with each other and I don't think she understands what I'm going through. I can't talk to her because she sees it superficially. I didn't ask to stay with her, but she insisted because I guess she thinks it's good karma. I'm trying to prepare and I don't want to be isolated at her house but I know a motel is expensive. I haven't reached anyone else because they have kids and I don't think the situation would be any more convenient. What do you think I should do? I don't want to go back and live with my mom. I'm the one with a full-time job, she hasn't worked in five years. I have a lot of money saved up, I'm just unsure about a few things. I need some space and independence and I can't get people to respect that. I have important tax info and forms at my house that I need to retrieve but I don't want to get ambushed.
