Yea, my XW went through several crashes as the guilt and status of her A fluctuated. It drove me nuts.
When my XW's A ended, she sunk into a depression and had to go get the help of a psychiatrist. The funny thing is that the medications made her more reasonable. Getting into therapy also helped her to end the self-damaging effects of the A. But, also it helped her to take the position that she needed to work on herself, by herself.
