Why am I so bad at this game, should I quit?

Hello all, I have been questioning whether I should take a break from this game. I also feel like I should be banned from this game because I am the worst player alive and should have my computer brutally smashed against my face lol but that's not point. Maybe I take league too seriously idk but then again we all kinda do because every loss makes you feel like your soul is being ripped out or maybe that's just me. I also don't feel like I could physically make myself stop playing, I have no ability to restrain myself so I guess the question is why do I play? Idk maybe because I think hey maybe this game will be different or maybe i'll do better or maybe i'll enjoy this but then i miss one cs and I feel my life crumbling apart and then I lose. I am very bad at this game...no one likes me, no one wants to play with me because I suck. What do I do? Keep playing and hope I improve and try to get better? Or smash my computer and destroy it to stop myself from playing i have no idea. I just wanted some advice lol I have no idea when league became my life...I just wanna be better so my friends aren't always losing cause I make them lose cause I'm a loser.
