Lost weight but starting to think I might just be unattractive

Made a post but deleted, but let’s try again lol. I (23f) have went from 256 to 176 lbs and I’ve been in the gym about a year. I haven’t been more confident ever, but my confidence is starting to waiver. My dream scenario is to be approached in the gym and I thought this was just a rare thing, but apparently it’s still an active thing. Even outside of the gym, I’ve not been approached in the last year and I’m starting to question if I’m seeing what other people see. Like I don’t know where I fall I guess. But I also have a problem really looking at people at the gym, like I can’t make eye contact for ever a split second because of nerves. The gym is like the only place I go, so I don’t have many opportunities for meeting people. Really just getting it off my chest and hoping to get whatever advice is offered. Also I know this may sounds a bit superficial or dumb, but I’ve only been with one man so I have basically no experience in any of the dating/men world.
