Dropped the game for 3 years and tried to get back... but

Okay so I dropped league for 3 years and now im back but like, I'm shit I'm trying to do everything right and stuff but I keep dying if I'm any other role other then top, but I don't want to play top all the time cause it gets boring. I'm too squishy playing the other roles. Just tried Jhin and I went 0/9

Idk anymore fml
