Mental health

TW: talks about bad mental health

I am 21 and have been diagnosed with 13 disorders Major depression, Anxiety (social, general, illness), ADHD, dissociation, derealization/depersonalization, BPD, DPD, Maladaptive daydreaming, PTSD, tics (not so much anymore). My mental health is the worst it's ever been and I don't know how to fix it. I'm in therapy and take meds, my parents (who I live with) don't take it seriously. They have a lot of narcissistic traits which doesn't make this easier. I've been on my own mentally for 11 years. I can't get a license or a car or a job. I feel completely stuck. What do I do?
