Was enjoying the game until I hit Gold

Was having a lot of fun climbing through Silver to get to Gold. Once I had climbed my way out of Silver I've felt that I've had no impact in any of my matches, and my teams usually refuse to work together. This most often comes from either one of the lanes losing or team fights lost, and the person who is doing poorly or someone else berating them spends most of the match typing instead of playing. I feel like I've been clamped after a few games of it, and the frequency that I get these players that spend most of the game flaming is 2-3 per match.

How am I supposed to overcome the flaming and people who stop trying? It's starting to get to me, and I have always been able to shrug it off. After basically losing over 10 games in a row through this I am at the point where it's starting to actually mess with my head: Am I even decent enough to climb more etc.

I mainly play support, so the team aspect of the game is what I am the most invested in every match. I do fine laning, but once people start to break down I just don't know what to do any more.
