Focusing just on familial distance and professional support, I think it's a go, particularly if you're ok with being 3000 miles from mom & dad. You'll be able to find new therapist and pdoc, so that shouldn't keep you from making the move. I would do it.

My BIL, J, works for Google (at their San Jose campus) and it's a nice area. I would have no reservations about finding a friend a home near where J lives.

Disclaimer: I live in the North Bay and love it, so I'm biased.
