Is it normal to find irritated or annoyed people bad?

I'm usually a bit "annoyed" if that describes it....?...With the word or phrases "get" "annoying" "take it elsewhere" "if you think I'm a bitch then tough". It implies disapproval to me & that I''m stupid and I'm not usually to well at bouncing off from that.. :(

The thing is I never do things on purpose to cause anybody problems or chaos in their lives unless they made me very mad but this wasn't the case at all here which I'll explain below:

I was in a quarrel with someone about me being indecisive as I have a history of changing my mind and just asking if they would tone down her and her friends bragging about their husbands but I got the response as I was a stupid blood sucking person and I have no business asking that amongst FRIENDS who I thought were reasonable people. One of them mentioned if I stopped changing my mind every 5 mins, I would get somewhere. Before I went to college, I cried. I didn't know what I did was wrong.o-o I didn't know where it came from but I know it has to stop because I'm sick and tired of thinking I'm the one with the problem all the time.

I don't know what to describe people who do this often when they confront somebody who annoys them. I know they are mature and they are right about it but I don't know how to handle it in a way that satisfies my mind and wellbeing..

This is what's been bothering me, can you please help?

Thank you
