I'm sorry your husband is being a jack@$$... You must be a tough cookie to deal with mental/verbal abuse on top of having this other problem. Put on your shield and turn ~him~ off. Let his words fall to the ground then step on them. He is very miserable with himself.
Maybe mention to your Dr. that you are in an abusive relationship, but I wouldn't try to show the samples. They don't respond well to that kind of evidence... but I'd at least tell doc that you've seen some stuff.
Try to stay calm and collected when speaking and definitely don't talk about turning yourself off, you will be "Baker Acted". In fact quit letting those type thoughts creep in and think about what's good in your life!... or all the stuff you still want to accomplish!
