I have been staying with my parents for the last few years while filing for disability and I still haven't been approved. My autistic ticks, nervous laughs, food icks are being taken as insults and my parents refuse to educate themselves. they want to believe i'm a monster so they want me to leave

I'm not sure where you're located, but if in the U.S. you can try your state's disability alliance/disability network for housing resource recommendations. You can also add your name to all income based rental properties in your area. If you have zero income I believe your rent starts at like $50
