Um. Harsh post incoming, but this kind of annoys me.
So you chose to stay in a relationship you knew was over, with your husband being honest at the time, and you drug yourself into a stupor to cope with it, and yet this thread is about your husband being angry?
At what point should he be content with the relationship?
If you are taking drugs to reduce your awareness and response times, how can he communicate with you normally?
I am sure you will get lots of posts about abusive men, who shout to control and intimidate.
However, it takes two to tango, and from what you describe in OP you are at least as much the cause of your current situation as your husband, perhaps more so because you have taken steps to reduce your awareness and responsibilities.
Make the decision you consciously chose not to years ago, of your own free will (no abuse).
Clean up.
Own your own decisions and life, instead of posting about how miserable the life you chose to remain in and drug yourself to sustain is.
