Should I quit ranked?

Hey guys!

I have been trying too hard to escape bronze. I don't have any friends who play league so I solo queue everytime. I play support because I enjoy playing them. Without me, the team has no survivability. When I play Sona, I have the ability to literally wipe the enemy team out with my ult. As a Soraka, my team's HP will always be in my hands. As a Janna, as soon as the enemy is about to kill my ADC, I can save them and when they dive I can easily repel them. I try my best each and every game. There many instances where I get completely outplayed by the enemy player and it is bound to happen, as I am still learning. But I always try my best. My most played champs are Janna and Sona.

But now I am starting to become exhausted. People very,very rarely communicate in bronze either with pings or words. I would accept toxicity (to some extent). As it would mean that the person is at least trying to win. Playing support has taught me map awareness to a large extent. I place wards and try to predict wherever the enemy might be. However, I feel I have no impact in games time to time. I am at the mercy of the ADC. If he can't do anything then neither can I.

I just do not know what to do. I played ranked so that I can test my skills and improve on them. But no matter what I try to do, defeat after defeat. Its just too much
