Man, I can relate, I was in a bad way when I was 24. I was very lonely and dangerously far down the incel path (though nobody called it that then) before I snapped out of it.

What I wish I had understood then is just how vast the bredth of human experience is. It may be hard to imagine right now given experiences you've had, but there are a lot of women who would be into you if given the chance. I know this is true because women are people. Quite a few of them are into men, of those quite a few are available and also yearning for a connection, and of those quite a few still are into some of your interests and particularly like various traits that describe you.

Rejection can be hard, but it only means it's not just right just now for just her, not that there's anything wrong with you.
