[ADVICE] Mentally disabled, but still want to improve my life! How can I at age 30?

Where do I begin? I’m still living at home with my parents and on long-term disability support. I’ve always struggled with being independent from my parents. I have been diagnosed with High Functioning Autism and generalized anxiety disorder as a teen. I’ve recently been diagnosed with depression with possible psychotic features (could be bipolar depression though, still not certain). I am currently on medication for my mental illness and going to therapy. I also weight 187lbs and have low energy (eating habits mostly).

I’ve tried working (in office jobs) before but it never worked out well for me. I do have ambitions for my dream jobs though. I want to help people in my own unique way, my mental health just gets in the way of that.

I really want to be able to move out and live on my own (and be a functioning adult) but not being able to work prevents me from doing so. I can’t move out on the amount my disability support gives me.

I went to film school in my early 20’s for screenwriting, but my mental health once again got in the way of pursing that. I am still paying off the student loan of that. I want to be able to go back to school for possibly business (I want to run my own business but have knowledge on how to run one properly), but I want to be able to properly handle that so I can be successful.

Where do I start? I’ve already made a vision plan, but I don’t think that is detailed enough! I want to reprogram my mindset and get a new outlook on life (which I’m currently working on).

Please help me out! Thanks for reading.
