I am sorry you are going through all of this. It's understandable that you are feeling awful Have you had a chance to speak with your T about everything? Also, have you and your H considered couples counseling while you try to work through things?

Given your situation, it seems pretty normal that you are very anxious. Change is stressful. Add betrayal and infidelity, and anyone would be a mess! (regardless of an anxiety Dx, which btw is NOBODY'S business)

Your marriage it between you and your H. I agree wholeheartedly that he needs to speak with his family to put them in their place (which is NOT in the middle of you two).

Best wishes to you. I hope you will take good care of yourself. And try to not be so hard on yourself. Please post and let us know how you are doing.

Rose
