Does it get better?

Nothing I do is working. I try my hardest to try and get better but every single time I make any kind of progress, it all comes crashing back down on me. I’ve tried reached out to friends/family, working on myself (hobbies, going out, exercising, better diet, less social media, ETC, ETC) but the thoughts do not go away at all. It started making me wonder if I’m some kind of lost cause.
