How can I start having fun playing League again?

I've only been playing for about a year but I'm literally about to quit. I'm a really quick learner and take things really competitively whatever it is. As I progressively got better and started playing ranked, especially the last few months. I can't even have fun, literally; even if I win.

The top 3 things that ruin the game are feeder's, afk's, and people who don't help the team as a whole. I'd be able to have fun if my team gave it a real shot at winning every game, but no. 10 min in top laner is 1/7, still trying to kill the enemy top, mid has 37 cs at 20 min, etc. Let's facecheck all bushes and sit on free trinket for 45 min, not buy a single ward.

I came into League knowing it was a strategy game and didnt really see that until I got better. But it's literally not even fun for me, if I don't hard carry the game it's basically gg. Free objectives, etc. Yeah this is a rant, but I don't know what to do, and I don't know what happened. I used to love playing this game and now it's literally a chore for me to play a match. Has anyone experienced this before? If I had the option to play any other game right now I'd drop league right now but my budget's tight getting into school and shit. Sigh
