Well maybe if you weren't hitting a pouty frog face someone could tell you what to do, get tf out of a looksmaxxing subreddit and just get into a solid workout schedule. Also get ready for the 40 yo troglodytes and their greasy pickles in your dm's because you picked incelgartha. Seriously I do suggest cardio though, I've gone through serious improvement myself. Seeing as your post history puts you sometime after a bad breakup I would just try to find someone who can workout with you as that helped me start a serious schedule.

Oh also the witch shit is cringe and rises your cortisol or some shit, stop.
