I'm the same height but have managed pretty well. Physical fitness certainly helps and changes people's perspective if you're worried about height. I had people make fun of me for my shortness back in my high school days but those were mostly guy friends, though it's easy to take personally. Being this height feels rough cause you're not short enough for sympathy but not tall enough for admiration based on height, so people think it's fine if they joke about it. Hell, I even had fat friends joke about it but I didn't want to make fun of them for being fat to show them how it felt, and being fat is something that's controllable.

Some women care but a lot do not (I'm not saying that just to make you feel better). I've seen guys shorter than me that I was jealous of. I wondered how they got such a good looking and taller than them female when I thought it wasn't possible. Tbh, it mostly comes down to demeaner. You'd be surprised how quickly you can change people's perception of you and your perception of yourself.

Here's where I'll level with you though. I have the same issue and it's not with height, it's with this mentality. Whether it be early life events, school days, etc. the issue is a mental thing and it will likely always be around or come and go. It's the same reason super attractive celebrities with all the money in the world go into deep bouts of depression, drugs, sometimes suicide, etc.

I'd tell you to talk more but I know the anxiety can make it near impossible. Do yourself a favor and look a some couples you see together. Not to poke fun at other people, but at some point, you'll say, "If they can find love, I can". Like I said, the issue is this mental barrier. Need to get counseling, medication, or find some way of breaking it down.
