welcome to SR. I'm so sorry your mom passed. (i lost my mother last may, but i am glad I was sober for her last days and funeral).
I hope you are on day 4 and feeling a bit more stable. the doctore appt. is a great idea and please be honest with him/her. if your insurance covers it, ask for a recommendation for some therapy to discuss your feelings about your family FTF.
post often and read a lot....join us on the gratitude threads (and even the whining threads). you are going to feel much better every day sober and you aredoing this for YOU too.
