I'm sorry you feel so down. I am in kind of the same "self hatred boat", however there are somethings I like about myself. When I take the time to think about these things, I actually begin to feel a lotbetter towards myself. I bet the same could work for you.
I also feel very similiartowards my family. I really don't want to be mean towards anyone, but my family can really drive me up the wall! You're not a bad person for getting annoyed.
Maybe talking to a T could help? Hoping ya feel better!
PS....luv Darren Criss too!
