I'm sorry, StrawBlond. I have a lot of the same issues you have and some more.
I notice in your post you said you are getting divorced but Wh is still there? I just wondered why, if you ever felt like telling that part. Maybe it's adding to your stress?
I have the tears too and for what it's worth, I asked IC for ideas of what I mourn and she suggested it could be other emotions coming out in crying form-anger is something she suggested and I buy that because I recognize what a horrible person Perv turned into.
Anyway...
That word I hate "compartmentalize" has actually helped me, though I hate to use it, but I wonder if it would help you? I used it when a holiday would come and we had too much to do in a day, where I would only think of one thing at one time. I know there are forces in the air around us that don't always let us think that way, but if you could make a list and somehow put an issue away for part of a day, maybe it could help?
I've also heard a term lately called "emotional exhaustion" that I have and it sounds like you may, also, kind of where everything runs together in our minds at once and all we do is cry. There's a lot online to read about it.
I hope some closure will come soon and I wish you peace.
