Maybe I can help you feel a little better about your lip. This is JanJaap van der Wal, he's a famous comedian here in the Netherlands, and he was born with a cleft lip (although I believe he had some surgery to minimize it, not 100% sure):
He's one of our most popular comedians: regular sold out standup shows, multiple tv shows (documentaries) he hosts, for years he was one of the regulars on the Dutch version of Have I Got News For You, and he hosted the Dutch version of the Daily Show. In other words, he's incredibly popular and well-liked, and absolutely nobody cares about his lip. People genuinely like looking at his work, and his work means thousands of people staring at him on stage and on the screen. He didn't let it hold him back, even though he talked about being bullied for it when he was a kid. He overcame that childhood trauma and achieved a lot of success. And, not that this is the most important thing, but he's now married to a very attractive Dutch actress and has a kid with her.
Just one example of someone with the same condition, leading a happy and succesful life, while being adored by a huge number of people who genuinely enjoy watching him.
Everyone has their thing, and even though you may not be what you yourself may consider traditionally attractive, that's no reason to hold yourself back from leading a happy and fullfilling life. Everyone deserves that. You do too.
