I had a weekend like you did. My problem is the palpitations and they're back. I hate this, too, and I wonder if I'll ever be free of this fear and watching. Watching everything my body does....You do need to structure your weekends. I think that's what is missing. You mentioned that you don't really have a problem with week days. So, that's good!
Let us know how your Monday goes!
Glad to hear you are feeling better. And yes anxiety does get better but you will have your high anxiety moments and know they will decrease if you can get your mind onto something else.
A Hobby.........great idea........send me some ideas too when your brainstorming. I need a hobby.
