I noticed you didn't mention your gambling addiction until the very end. Huge problem. Do you really mean you have been clean just 13 days or did you mean 13 years?

If only days, my suggestion would be to divorce. Work on your sobriety. Don't try to have another relationship until you have been clean for more than a year.

Also, along with your gambling, it may help to work on your emotional regulation a bit. It seems that when problems arise you react in a very dramatic fashion (having attacks, instead of paying attention to what she is telling you you are focused on your "mental health deteriorating").

Also, respect her request to stop looking at her Instagram.
