[LFG] I'm looking for a team Support Bronze Main

I have been playing league for three months. Yes I know many people say "Oh, you should play longer before looking for any teams" But you know what I play every single day just trying to get better and sometimes I feel like I'm not getting any better. I feel like quitting the game because one player in every game i play in either flames me or just tells me I suck and uninstall. I try to support my ADC and every time the game starts i ask "Are we playing passively early game and aggressive late game or are we going to be aggressive all the way through?" They say passively and when its like 5-7 minutes in the game the ADC goes in and i follow up and tank the shots but when the ADC is nearly below half health and the enemy ADC is on a last hit to be killed, the ADC I support goes back as I tank for my ADC to get a kill and doesn't get it and I end up dying and then my ADC i support flames at me just for following him/her up so my ADC could get a kill. I'm open to learn more things especially strategies. I don't like to be trampled on for my bad plays, instead I like someone to tell me how to do more better in the situation. I just don't want to feel like a moron when I play. Even if I'm bronze I deserve to still be treated as a League Player as everyone else on here.
