Whats the point in playing League?

I like ranked it's fun, but im bronze V :/... I worked very hard to get to bronze iv to get demoted due to trolls and toxic team mates. I'm good at top lane only :/... I will go with what people force me to play though and not complain. I usually am stuck with support and im really terrible at this role... So every game they force me to support, I do try my hardest but we lose. They send me hate messages, tell the enemey team to report me, tell me to kill myself and slit my wrist.. But I did not choose this support role, I was forced into it and I do suck at it. So, I'm being reported 10 times a game just because I'm not a pro at support ?
