How do I win my series as a support main?

As a support main, I can't win games. I just lost my series for the fifth time in bronze five. BRONZE FIVE. It makes me so angry I got placed in a division so low after coming from silver. That aside. As the support, the game is literally out of my control. I love the role, but damn I just can't win. I'm trying my best, but I don't do damage. I play and recently . I feel like I'm the only one who ever wards, then despite me having my pink ward and my three free sightstone wards up, I get blammed for no vision, because my wards are the only ones there. I get toxic ad carry mains. I also get the ad carries who have no idea what auto attacking is. Everyone acts like support is so easy, in reality I think it's the hardest role in this game. You've basically got to pray that your ad carry is willing to work with you, and not flame you for dying trying to save, or saving, his ass.

I've tried everything I can think of to be the best support possible. I've tried alternate starts, different builds, itemizing against the enemy team, adjusting my runes and masteries, watching LCS, trying to watch my attitude in chat when playing, and nothing works.

How do I carry ranked solo queue?
