Yikes. Since no one else has commented... . I'll say that whatever your situation... . you have to find a way to take care of you. Even if it is not physically getting away - find a way to untangle from the emotional enmeshment (is that a word?)... .

read, watch movies, mindfulnessn exercises. If you are going to stay sane you will have to learn to detach w love.
Read the lessons. First you will learn how to stop making it worse! ( invalidating comments jade-ing)... . after that you'll learn how to make it better (boundaries, validation, learning to listen). Good luck
Ps the lessons are om the right.
