stress/anger management

I’ve always been one of those people who gets stressed at everything. When I say everything, I pretty much mean any small inconvenience will make me so stressed, I sometimes have to audibly scream. I’ll give some examples of what has made me stressed and how I’ve reacted to it. As a disclaimer, I have NEVER and would never physically hurt anyone when I’m angry but when I’m stressed, I get angry because I’m stressed and that means I start reacting in horrible ways: - road rage. I know this is a common one but this will literally put me in a bad mood for the rest of the drive home and even afterwards. I had an incident the other day and when it happened, I couldn’t stop literally shouting about it in my car and when I got home I was still shouting about it because it made me stressed. That was one incident where someone just pulled out on me at a junction. - if ever I have something coming up: a job interview, an exam when I was studying etc, I would get so stressed out. Thing is many people would read this and think “oh that’s normal.” No. It’s. Not. When I was at university, I was writing a dissertation and I got so stressed one day I started crying, screaming, I kept smacking my laptop and I was hyperventilating. There’s being stressed and there’s that. - minor inconveniences make me angry or stressed. For example, when I have to go pick my boyfriend up from work and it’s dark and there’s loads of traffic (I don’t like the route to his workplace because it’s windy and narrow, I can’t see even with glasses bc I have night blindness), if I have gone shopping and forgotten something, if someone says something that makes me question something I’ve done. This one’s very specific but for example, if I bought myself a pink top, someone looked at it and said “why would you get that colour, you should’ve got the orange one”, I’d then stress about it and not stop thinking about it all day, I’d rant about it, maybe even cry about it. Something as minor as someone not liking the top I bought. Something similar to this happened to me the other day and it made me cry and stress about my decision. - One thing about me that I hate to admit is that I do take my stress out on other people. If I’m extremely stressed, hyperventilating, crying etc, if someone tells me to calm down, I go insane at them. Even if they don’t do that and they genuinely just try and help me, I snap at them and then I get even more stressed because now I’ve just argued with someone. I don’t mean to but I just do. I feel really bad after because I know they’re just trying to help. And the thing is, it won’t even be a huge thing I’m stressing over. It’ll be something so minor and so small but I’m so horrible and just not a nice person to be around when I’m stressed. I was wondering if anyone knew if there’s any reason I could be this way? Should I see someone? Does this sound like any sort of mental disorder? Honestly sometimes I think I might have one. Because it is the most minor things that makes me like this and I am literally known as the “stress head” of my family. My boyfriend even jokes that I’ll have a stress related heart attack at the age of 26 or something. It is obviously affecting relationships because I’m not nice to people when I’m stressed, especially my boyfriend or my mom. Just want to know what I can do to chill the fuck out
