Still Living with Dad at 30

I'm 30 years old and had to move back in with my dad recently. I feel ashamed about this. I live in the US where the archetypal norm is to be out of your parents home by the time you are 18. I have struggled with alcoholism and severe anxiety and depression through my 20s, and ended up living in my car by the time I was 29. Is it OK that I still live with my dad now and will probably have to for the next year or two in order to fixmy life?
