I am not proud of this but at least let me explain

I am not someone who gets mad easily. Generally I am a very calm presence I would say but when someone makes me mad it's like everything's going red. Like I am no longer in control of myself. I even hurt these people and I THINK it was because my parents used to hit, kick eg me when I was younger and that I kinda adapted that bad habit.

It is usually almost impossible for someone to anger me this much but when it comes to my family it gets there much faster:

My sister, our friend and I where in a city 30 minutes away from our village. At first I didn't want to go because I had an important medical appointment but my sister begged me to come along so I eventually gave in and drove along with them.

While being there I kind of forgot the time (which was definitely my fault) and when I looked at the time again after a few ours I noticed my appointment was supposed to be in the next 20 minutes. I told that my sister and hoped she would drive me to my appointment (which would take 15 minutes as my appointment was in a different town) but she just screamed something like she still wanted to go to that clothing store and she wanted to take her time, I should have known, she's not going to help me out eg.

It was really disappointing for me and it angered me a lot as this wasn't a big favor and a normal sibling would have helped me out. Also she went to the exact same store 2 days earlier and figured that she didn't like anything so it really felt like she was trying to provoke me as she does this a lot.

At some point she actually decided to drive me but on our way to the car she kept insulting and screaming at me though I wanted this just to be over.

At that point I was overwhelmed, stressed and annoyed that I felt the urge to hit her. I am working hard on not hurting anybody ever again but this is still something I can't really control as it's like a gigantic "force" taking over me. So in order to not do anything bad to her I was walking faster to get her out of my sight.

At this point my friend was also very annoyed and shouted at me not to run away and not to be that childish. I started crying due to the overwhelming feeling and shouted that I am doing it to not hit my sister but she still acted like I was being childish.

This was very frustrating to me as she's my best friend and she knows about my struggles and yet she acted like the adult who knows it alls better when in fact she doesn't. (That's kind of a bad habit of her she's just one year older and has had made many wrong decisions throughout her life which I had to help her get out and yet she still acts like I'm the small child who doesn't know anything though we are all basically still children)

She also thinks she can analize all of my behaviors because she has been learning a little bit about psychology in her training to become an occupational therapist for like four months.

I know my behavior and reaction was wrong. But both of them were wrong too. They don't see it at all which is frustrating to me. That's only the way I see it though hahaha so if u made it that far: Was I the only one who was acting wrong? Oh and in case you understand me: do you know how I can stop myself from hurting other people/ how I can control myself better?
