Am I really unattractive?

Am I really that unattractive? I know attraction is subjective, but it feels like too many people either find me ugly or just not their type. Every time I try to be myself or just exist in public, no one approaches me or even talks to me. It’s discouraging.

I’ve elevated my appearance—not just to find a man, but to improve my chances. I’m not saying I changed my looks just to get a boyfriend, but in a way, I hoped it would help. I know I’m only 19 and have the rest of my life ahead of me, but I really do want a relationship. I thought it would be easier, but it’s not.

Meanwhile, all my friends and people I know are getting into relationships, and I can’t help but feel jealous. I’ve never been in one, and I don’t know why. I work on myself—I have my own hobbies, I go to school, I have a job. I’ve been putting in the effort, but I still feel stuck.

Sorry for the long post, but if anyone has advice, I’d really appreciate it. I just don’t know what’s wrong.
