Im 30 and my mom doesn't let me use her car to take care of my tasks?

She lets my 27yr old Bro and 21 yr old sister but not me, ever. Im unemployed but can't use it to look for work or go to walk in interviews. I have no phone and she only sometimes lets me do job searches for maybe 10-15mins every now and then before she goes to bed -shes a RN. I can't go to grocery store, can't buy myself basic hygenie supplies etc. Im just stuck at home 24/7 and I dont have a dollar to my name. she's also the only one telling me im not gay despite everyone in the world calling me a fxggxt. When I tell her what Im dealing with she says you just have paranoia, delusions, auditory hallucinations, mild psychosis and severe depression and social anxiety and doesn't believe people would say this to others let alone doctors teachers strangers judges and attorneys because why would they risk their jobs over you. I feel like im being babied so hard and even if i left home i have no family or friends to turn to and would die on the streets due to poverty and neglect. I've been homeless for a week before in 2017 while in college before dropping out and people won't look me in the eyes let alone spare me any change other than a rude comment
