Is it normal if i wish i felt different about people?

I get annoyed very easily. There are those people who are annoying but it is up to the others if it bothers them. For me, it does bother. I wish I didn't get annoyed so easily because I can just move on and not focus on how annoying that person is plus prevent a loss of a friendship. I feel like due to my nerves, I have lost a few friends and a few potential friends because they just got on my nerves and I obviously react to it whether straight up telling them or by my attitude. I also feel like that was one of the reasons why my bf and I broke up because he would annoy me so much and I understood it was only for that moment so I gave it a few chances but eventually my nerves exploded. Right now I have a roommate who is getting on my last nerve and I believe she is starting to notice. I wouldn't be surprised if she hasn't though because she is so blind, that's one of the annoying things about her. She has no idea that our other roommates don't want her present because it bothers them less so they don't show it...although when she is not around, they can't help but talk how annoying she is. I wish I was like them in a way because they have patience so there's no tension between them as opposed to there is starting to be some tension between me and her since I'm impatient. Why? Again because I naturally show when I'm annoyed. I can't help it. What doesn't help either is I can be bipolar where at one point she annoys me and another time I can stand her. When I can stand her, I try to let it stay that way because maybe it isn't worth causing tension with her. But I don't know some people like me can't help but get irritated and need to let others know where they stand and I feel like thats my job to let our roommate know she's annoying and she is not welcomed since the others cannot defend themselves. So either I let her know or TRY and chill out but how? Its a lot of work. In general though, certain people can on my nerves. So I am not a people person where yeah I can see you're a b*tch, you*re slow and annoying, you*re a brat, etc and still stand you. I CANNOT do that. I don't get along with everybody. If a certain aspect annoys me about you, it goes downhill from there. I can't look passed it. Its this tall wall built out of annoyances from you that I can't knock down.
