😢feel worthless. Please no judgement

So a friend asked me to come over and they smoke green and I don't. But I haven't smoked in 3 years. Well I ended up smoking, from an erge of smelling it for some reason. Well I was with him 'alone' and we kinda had sex. And I'm married. We been arguing alot and I've been feeling lonely anyways, as well has invisible kinda. (When I smoke I can't feel my body and I get a drunk like feeling) my mind goes fuzzy and can't remember alot. But I don't know what to do. All of a sudden I get a panic attack and finding myself at his house and then smoking and sex. What am I gonna do let alone live life with a lie.
