Support Main, what should I be focusing on in my games? [op.gg included]

Hey r/SummonerSchool!

I'm noticing that I lose a lot of my games, especially outside the support role, but sometimes as a support as well I'll go on a bit of a negative patch.

I think that perhaps my warding and general game sense isn't as good as it could be, and my map awareness is not as good as it once was... I was in gold in season 3, took a break soon after placements and have found myself struggling to get out of bronze this season.

Does anyone have any advice that I could focus on to try to climb?

Thanks all!
