In 2016 or 2017 I was inpatient and had a wonderful psychiatry resident who since then has finished residency and stayed in the area as a practicing psychiatrist in a large clinic. She herself has an anxiety disorder. She mentioned that people without such disorders take for granted stuff, like, showing up for work every day. But if you have crippling anxiety, simple things (simple for others) are made difficult and you complete many impressive feats just getting through an ordinary day.

You need such friends and practitioners in your life who understand it.

Pat yourself on the back for doing what you have been doing, and, of course, get a lawyer ASAP. I am actually quite surprised that your dad, being the doer that he is, still has not realized that you need a lawyer.
