Just because a woman doesn't like you back doesn't mean she's perfect. Why am I saying this? It's because that's how it feels like. The natural human assumption is if a person doesn't like us, they're better than us. Do not feel bad, it's human nature so it means that it's an emotional reaction and not a logical one. It's not based on facts, it's based on feelings.
What you have to get through your head is that these women who reject who also have flaws. These women that reject you also feel insecure about their bodies. These women who reject you also feel like they're not living up to their own standards. They also show a certain life that they don't live but trying to do just to impress people.
We let ourselves be fooled by the facades that people show us, by their smiles or their Instagram stories and we think they're perfect. As a result, we look back at ourselves and say "fuck man, she must be so much better than me".
You have to make the mental effort to really think about the benefits of her not liking you back. Deeply think about it because if you don't, your brain would naturally sway in the other direction and that's the self-loathing and blaming yourself. It's something that I've had to do as well.
It really sucks when you like a person but she doesn't like you back, especially if you're having a hard time liking people. It really does suck but what I've learned from it is that in those moments, it's when you'll know how strong you are as a person.
