ANNOYING!

Don't people see that I am annoyed and I want to be left alone? I see it when other people are annoyed and don't want to be around anybody! I just want to be left alone and do what I can to get through my day. I want to scream at them but I know its not the right thing to do. I don't care if some people are around me but certain ones I don't want them around me just because they say things that piss me off!! I know there are people that your not going to like in life but I don't understand why they have to talk to me. Don't they get it when I walk away when they are talking to me or when I talk to someone else when they start talking to me. I don't want to be a bitch and say you need to shut up and stop talking to me. It is just getting really annoying! I want to freak out on some people. I hate it when people know they annoy you but keep coming around u or keep trying to talk to u! I am trying to be the nicest person I can be but it is getting really hard! I just want to be left alone and I know my nonverbals tell them that!
