Don't know why this bothers me so much?

It bothers you so much because she has hurt you. I don't really know what to say to you but it sounds like this situation must be be bloody awful for you!! First I guess you could try and help to get her meds sorted, this would be a start. If your wife isn't careful she might loose you in the future, how would she feel then? People only can tolerate so much. Wish you all the best.
