I'm sorry to hear what's going on but your W is in a full blown A with OM probably has been for some time. Packing your bags won't change that for now.
You need to get back to DB basics, Work on you, GAL, act as if, move on with you life as if your M is done.
The A with OM will play itself out, you have no control over that. You just have to get on with you. I'm so sorry I really feel for you.
