KS-- Didn't realize we were both ACOA. Yep, we can check off most (but not usually all) of these feelings. Have you ever gone to AlAnon? I have been going since Oct, and it has made a huge difference to me and my awareness.
I miss my kids when they are away, too. S is at summer camp with x for the week, and both will be gone with him for a week at the end of the summer. Ick. Making lots of plans to fill the time.
