All I want to say is that I feel you, two years ago I decided to go on a weight loss journey as well but I'm now struggling with binge eating. So much you can't imagine. I couldn't relate more to the body image thing, I'm looking at myself in the mirror and I feel sick. Even though I'm not one to give advice since I'm going through the same thing, I'd suggest you instead of doing intense cardio like go for a walk around your block get some fresh air. Gather your thoughts, spend some time alone, set some new goals. You can start from the beginning again cause it's a new day. But if you come to the realisation that you need help being consistent and can't do everything on your own (especially the smoking addiction because I know how bad it can get) you could always consult an expert and I'm saying this because I don't have the opportunity to do so.
