AD's anti-depressant medication. But, if I understand it, depending on what kind of depression one is having...helps the doctor to know which kind of medication to put you on. So, that is why you need to explain the panick feelings.
I need to catch up on your thread, but I would think your H and the M problems cause depression by itself. Feeling that he is going to go off on you in a fit of anger, or just being upset with you, may bring on panick attacks.
If you can reach the place that you show him his being upset or frustrated at you for losing papers (or whatever the next thing might be) does not affect you.....I think he'll learn that action doesn't work any more.
Him discussing anything that has to do with his appartment is disrespectfult to you and I think if it were me, I would tell him that I would not discuss those subjects that were disrespectufl to me or our family or M. If you aren't confined to a car the next time....you can say that and then walk away from him.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
