why am I a hateful person

I always complain how I want a bf to myself and why I can never get one and I figured out why…I’m mean. But at the same time guys that do talk to me are annoying people that I don’t feel the need to start a conversation up with. And I’m not talking about like talking to someone who’s interested in me I mean normal questions. Examples- “can I have a pen” “F no” “Can I borrow a paper” “shut the hell up” “what’s your name” “none of your god*amn business” WHY AM I MEAN?? I GET SO ANNOYED AT SCHOOL FOR NO REASON I’m usually really nice when girls ask these questions and sometimes when guys I don’t know, but it’s usually guys I don’t personally know but I know OF. And they have a bad reputation of being bad people so I’m just automatically mean.
