I want to control my anger and stop being so overreactive and negative. Where do I begin?

for context, i’ve grown to be a very emotional and also angry person at times. i take a lot of things personally, and i’m a very defensive person which. causes me to constantly be tense. it also doesn’t help that i suffer from a lot of anxiety, so i’m very reactive in hopes to guard myself and my emotions. I want to finally let go of my ego!!!

i’ve never properly mediated, but i think it could be something that will finally help me. i want to be more calmer and live life at ease for once. in terms of meditating, where should i start? what do i listen to/guided practices, any physical additions, things to buy if necessary, where to do this, etc? Any help would be so appreciated!!
