How do I forget my bad looks when trying to date?

I see real life stories of people who are missing limbs, paralysed and “ugly” finding “out of their league partners”. They’re confident, driven and just don’t give a fuck. However, I assume that behind closed doors they have terrible days from hate, bullying etc. Most of the responses to these sort of couples that I see is that the guy must be rich or packing. That’s the sort of culture we’ve created from our own doing and I think its fucking terrible. And it comes out of jealousy for sure. People think that it’s not fair or right that someone so “ugly and disabled” can get someone so beautiful and “normal”.

And the purpose of this post is not putting these people down. I’m happy that those sort of couples exist, cases where looks don’t define a relationship. I just want to be able to bypass my looks when attempting to date. I’m a 20 year old(M) and by society’s judgement, I’m not an attractive guy. I struggle with acne and my features aren’t what most people would deem attractive. I’ve tried by best to combat things I can change like acne. I’m still trying even when things aren’t working. I’ve also tried to get in good physical shape but there are a lot of things that hold me back. I have early satiety which means that I get full after a small amount of food. My digestive system doesn’t work properly.

I struggle to breathe with asthma and have other psychological illnesses. I’m not making excuses but it is hard to bypass these things as well. Whenever I’m dating, I don’t properly commit myself because I think that she won’t like me because of these illnesses. I think that she won’t be able to handle all of it and I how hard it will be to tell her all of these things( if things did work out) .

But the main thing is that when I’m flirting with a girl I don’t want to think that she’s focusing on my looks. If it doesn’t work out, I don’t want to blame it on my looks. I don’t want to not fully commit and not try to win her over because I think that my looks aren’t enough. Any advice? Do I consider therapy and what type?

TL;DR: How do I bypass by bad looks when attempting to date?
