I need some help/advice

I got back from my tournament and I've never been so angry.

Imma keep it short. I lost my first match, I got mad, won my second easily, but only faced a problem when it came to my third cuz I was wrestling my teammate (I lost btw).

When it was first announced that I'd be going against him I was scared, but the closer we got to the mat, the less scared I was and then the match started. I went aggressive but calculated like always and that worked pretty good. He got a takedown or something on me and got to my back or something, idk 🤷🏿‍♂️ he scored points. I did a takedown and stuff and got some points. Everything was good til we stayed on the ground.

I kept trying to get him to his back but everything I did failed. I saw him waiting for clock to go down a lot. I don't know if what he was doing was an actual strategy but basically, he got more points then me and made sure I didn't get him to his back, he didn't wrestle back or anything, he was on the ground taking everything. He won but in my opinion I don't think it should've counted.

He didn't even do much after getting the points, just laid there like a rock

After I lost and was walking back to the bleachers to get my stuff and leave, fellas kept giving me the "Good match" "That was a great fight" and stuff like that. It was not a good match 🤦🏿‍♂️. I was so mad. I was mad at the strategy he used, I was mad at whoever set it up so I had to wrestle my own friend, I was mad at myself for not standing him up more often, I was mad at him for not trying, and I don't have anyone to wrestle today so I'm literally just walking around with built up steam and nowhere to blow it off.

Sorry I kinda went long. I was going to ask how do I stop being so angry at him? I'm going to have to see him at school again on Monday. Should I get revenge when we're on the mats at practice or what? I've tried breathing it out and taking a nap and doing a bunch of pushups but it's not working. All I can think about is how I could've pinned him and how he so much weaker than me. But that's one of my best friends so I don't know what to do.

What do I do?
