I Am Miserable

Yesterday some lady backed into my car while I was parked. It was late last night so I just took down her name and number and I thought that was enough because my friend parents said it would be. So today I let my mom know what happened and she automatically assumed it was my fault and was not being very kind. My car is under her insurance so I had to let her know. I confronted my mom about how I didn't like how she jumped to conclusions and was being mean. She took offense to me defending myself and claimed I was being mean and spoiled. Now she states that she doesn't like how our relationship is going and is asking that I move out. I work a part-time job and she is demanding I find another one to cover my rent expenses. I have been actively looking for a full-time job but so far no luck. I am not sure why she feels she needs me to leave I do so much for her on a daily basis. Clean her house and dishes install her shower head and and shower caddy and let her eat my groceries I got for myself, but apparently she thinks I am spoiled and a freeloader. I mean I was planning on moving out once stable but not sure why it had to come to this.
