Living on your own for the first time is an extremely stressful undertaking even when you aren't symptomatic. $800.00 isn't enough for rent, utilities, your phone, transportation, and life's incidentals. Plus it isn't just rent. It's the security deposit and last month's rent you have to pay up front. If you have a pet, there is a pet deposit. If you think you qualify for a supervised living situation, you need your psychiatrist and a social worker to do all that paperwork. Also waiting lists are long. You could wait a year or more for a placement.

The way this works is if you already have a home and it isn't an emergency homelessness problem, you'll be put at the bottom of the list. I have two sisters living in group homes. One got her placement because the state hospital she was long term placed in closed her wing. It was a direct transfer state hospital to group home. My second sister was in a nursing home for years with MS and psychiatric illnesses until a group home opened up for her. She was considered low priority because she had a bed in a nursing home.

I can understand the stress of living with mentally ill parents, but it doesn't sound like you are in the best space to live on your own. You can get the paperwork started for a supervised living arrangement, but just know it'll be a long wait.
