Struggling with Multiple Mental Health Disorders and Neglectful Family

I was born with autism, schizophrenia, adhd, add, bipolar, ocd, anxiety disorder, and depression. my family is neglectful and doesn't care for me. I take a lot of pills for my disorders, and I get sick almost every day. sometimes I don't know what to do, so I go to psych wards, and the medicine they give me makes me worse, especially with anxiety. I always talk down on myself and have a bad output on myself. is there something that I can do to manage myself that helps. my coping skills don't help me and I've tried using the 5 senses and it doesn't help with the fact I am numb both physically and emotionally.
