If your insurance covers it you might want to check into a rehab facility. Most employers will let you off for stress leave if you get a doctor's (not your husband) note.
If you do not want to or can't do this. Move in with a trusted friend for a long weekend or more and dry out there. You will most likely not sleep much during that time. So load up on things that will occupy your time and make you feel cozy (i.e, movies, books, games, ice cream, etc).
Attend a few open both AA and Al-anon meetings, and, if it makes you feel more comfortable, where you will not run into people you know. If you can't do that there a lots of meetings and other resources on line.
Yes your husband is an abuser. Just because he is a doc does not mean anything. Lot's of docs in AA and other programs.
