There's probably 5 things I would say to you:
1. Figure out whether you are a mental person, or a physical person
For mental people, mind techniques and things like meditation work for relaxing or calming them
For physical people, they need to express themselves physically in order to get in a state of calm
Based on which one you are - have activities you can do to let off steam and get in a state to think properly
I know for me - meditation, breathing exercises - none of that stuff has ever worked because I know I'm not changing my physical environment and as soon as I'm done everything will be the same. I need to be physically and practically doing things
2. Put all your energy and effort into finding meaning in life, and developing a well rounded life
If you don't have projects, a way to make money you find interesting or challenging, or things you find meaningful in life - you have no rock or no well to go to in times of chaos or when life is going shit
You need to find things within your control that you can work on in your life that will give you peace and balance. It might be woodwork, artistry, making music and playing instruments, starting a business, working on cars - anything that you can get good at and stick at
3. Develop discipline and become an adult
You mention spending all day at the beach, or blowing steam partying
The problem with these things is they are recreational. You can't reward yourself for being angry by going and doing things which don't involve discipline
Doing hard shit pushes down and crushes your ego, and amplifies your values. Do more hard shit that keeps you accountable and requires you to be disciplined. It increases your self control, patience and perspective in life
Take the challenge of being a grown up, and doing more things you don't like that provide you with longer term rewards
4. Consider joining an anger management group in person, or an Facebook or online group
Where you can talk to other people going through the same thing, and you can perhaps encourage each other or offer each other tips
5. Consider professional advice
It's very possible you may naturally be inclined to anger more quickly - whether that's from your genes or the way you think
Consider seeing someone for a professional opinion on your situation
I'd stay away from meds if you can though.
Exercise, eat healthy, think positive, make money, have projects to do and keep you busy, think about and give to people other than yourself, go travelling and go visit poor countries to realise how lucky you are, continually grow yourself
Just keep engaged in life and eventually things change over time
