If you don't tell them you are getting help, they won't know. You should do what you need to for yourself. You are NOT responsible for him being depressed--he is--he is responsible for himself. So no need to feel guilty. (I know, I know, easier said than done.)

OK to take up forum space--we are here to help each other. Perfectly fine to reach out for help here. Do call and get yourself some help. Take care!
