What is wrong with me? Am I really such a weirdo?

do not care about people who don't appreciate you. just because they're a bunch of idiots does not make u a weirdo. it's hard to find quality people, it's very hard. be strong and just be yourself. btw, i'm a vegan for the same reasons, but i'm a strong character, you don't need to explain yourself to anyone. do they explain to you? you don't owe anyone any explanation for you choices in anything.
