You seem fine with who you are and that is everyone's goal. I'm a pretty nice person all things considered and I don't like everyone.....it's more common for me to not like a person than it is for me to like them. I don't go out of my way to be an azz to them, but they probably usually know I dislike their traits. That doesn't make me not nice.

It's only important to be lovable if it's important to you. I can not assign importance to something for you. If you don't care about being lovable, then don't care. If you do, then you do.

Very few people in this world are unlovable. For every highly flawed person, there is an equally flawed person who will love them just as they are.
