Struggling to relax

Hi. So I’m a binger in everything I do. I simply can not moderate. Thankfully I am managing the art of abstinence. Nothing is far better than a little. I’m far healthier and lost allot of weight as I’m throwing myself in to exercise and healthy eating. But my main problem is I simply can’t relax. I can’t sit and watch a tv programme or a film.
It is worse the healthier I am. Strangely I actually miss a hangover following a binge when I’m happy to waste a day on the sofa watching tv and eating junk because I was “relaxed”. I’m sure this is related to having adhd (undiagnosed). The only thing I feel will remove this angst is a sesh and/ or eating junk which I really don’t want to keep doing as I’m getting older. Does anyone have any suggestions?
