Making myself sick about an imagined future that might not even happen--STOP and get back to work!
What's good is you're realizing this & telling yourself to stop! My C told me to concentrate on just today, that was key to mental health. Sounds easy right? As we know none of this is easy. But if it helps, I'll remind you: Keep your mind on today!
Just keep on your path, you are doing great - Really! Soon this ucky legal/house stuff will be done, that will be a relief I think. It does suck you have to leave the house so X can get his stuff, in many trips it seems - is he about done? Once you have it back to yourself & start working on those home improvement projects I bet you'll feel much better. Thinking of you & sending hugs ((((Aver))))).
