If I can't play this game in a healthy way should I quicksell my squad?

I had 8-0, lost my 9th game and I started raging like a madman. I went to play another games and of course - loses. I felt I was better but I was playing dumb because of my rage and I started trolling. I also want to smash my controller into the wall and break my palms. I cannot control myself.

I think there's no hope for me, it always ends like this. I think I should just qs my team and forget about this game. What do you think?
