You can't win them all! But I'm really sorry to hear about your struggles. I can assure you, though, that the incel way is nothing but a dead end and I've literally never seen anyone walk out from their cult feeling better about themselves. You definitely deserve a lot better than hopping into that crab bucket of absolute misery. Don't even do that to yourself when you don't have to.
You sound really frustrated, which can't an easy state of being. One could easily lose sleep over it. I hope you don't mind me snooping, but I had the nagging suspicion that you're socially anxious, which you confirm in another post. Addressing the SA and your anger will improve your quality of life and it'll make your dating life a whole lot easier in the future. You want to feel your best to be at your best. Therapy, meds, CBT (=cognitive behavioral therapy) techniques and exposure therapy can work miracles on social anxiety, but there are also free CBT resources available - even CBT apps and videos on youtube and other websites that you can use. I can vouch for these methods as someone who used to have debilitating social anxiety. If you send me a PM I can also share some resources with you.
Maybe you could do with some gym & styling tips from the men's fashion and styling subs? Do you have friends who could have a movie night with you or take you out for some beers to cheer you up? I feel like everybody could do with a little emotional support from friends or friendly people after trials and tribulations like these, so there's also r/bropill and r/DadForAMinute for support and some advice. Also the tip from the other commenter about making female friends is pretty spot on. If you want to humanize women (i.e. ease some of that anger you feel) and learn how to talk to women in general, there are fewer things as effective as having women as friends. Back in the days people used to also find their girlfriends and boyfriends through friends, so that's something else to keep in mind. Maybe they could wing woman ya, or help you with styling, etc.
TD;LR: Give yourself a pat on the back for good effort, you've put yourself out there like a champion and that's something to be proud of. Make friends (with women). Check out CBT techniques for social anxiety and emotional regulation.
