I easily get into fights with people who trigger me

Anger is usually caused by being powerless. So take responsibility and increase your agency and power over your life otherwise you will always be angry and lash out.

How is your money situation? It probably sucks if you're stuck in your parents house. So really you're only at your inability to make money. Not your parents nor anybody else. If you made more money you could put yourself in whatever environment you want to and remove any outside stressor.

So stop blaming other people and other situations that don't have to do with your ability to become free i.e. your financial independence. 

If you feel like a trapped animal in your life of course you're occasionally gonna lash out and hurt others or yourself in frustration.

I don’t hate people. I’m not angry and grumpy all the time nor is it my default. I’m actually a very nice guy . I never started a fight with anyone. 
I always wish to live in peace but The world is not peaceful. most people are not peaceful..at least in my life . That’s the issue . 

I didn't say you hate people. I said you seemingly, based on my intepretation of your post, that you don't tolerate others' differences.
