Sorry things are tough right now. This is all so very hard.
I agree with dim not dark. Remember that her wanting to be alone is not about you or an OM. It's about her needing space to figure things out.
That's why I like the phrase "love them from a distance". It's the most loving and kind thing we can do for them right now.
As far as AD's, that's a very individual decision. I'm not on any, but did discuss it with my IC in the early months after bomb. I wanted to try focusing on myself and the kids in combination with yoga and taking better care of myself before trying meds. I did end up feeling much better.
Getting yourself to a good place is important, so think of different ways to help make that happen.
Hang in there!
