I want to start recovery

Hey guys, well, as you readed on the title, I want to start recovery, because I think I have a serious problem with PM tht is affecting my life in a bad way. I'm 21, I have always been very shy and this has affected my relations with everyone, specially with womens. My hearth races every time I speak to a woman, I get very nervous and I feel like my tongue gets tangled up when talking.

When I "discovered" masturbation (I think that I was 13), I thought that I had found the best of this life, it made me feel good and relaxed when I was lonely and when I combined it with porn I thought that I could not be better and that it would always be, but the problems started to appear: I suffer from anxiety, if I don't eat or masturbate, I feel like i'm going crazy, I get angry and want to destroy f*cking everything and when I do one of the two things, I'm satisfied only for a couple of hours and the anxiety returns. I raised 20 pounds in 6 months for this (for excesive eating, of course), thankfully, I'm tall and I barely look fat.

And that's not all, apart from the problems to relate to people, I also have problems related to my sexual health: I can't keep a hard boner (And my ex GF could confirm this). I thought it was because of nerves, but it's just the fact that I need a really explicit scene to get excited. In short: porn. I think it's just a miracle that I don't suffer premature ejaculation.

This has already affected me for a long time and I feel it is time for a change and this is why I want to start the recovery. I want to do whatever it takes to improve my mental and physical health and of course, also my way of relating to people.

I await everyone's comments and thank you for any advice you can give me. Greetings from Colombia lml
