It has been 4 years but finally...
I'm Diamond. It took a lot of focus on learning matchups, map awareness, mastering mechanics, and knowing when to make plays but I have finally reached Diamond as a support main! I started silver when I first played, by the end of the next season I was in gold, a year after that and plat, and now this year I have joined Galio's Beserkers in Diamond rank.
can work wonders for your survivablity. Against an oppressive AP champion try getting
first instead. Every game you need to analyze what you need for the situation at hand. Guides online are great starting points but they can't cover everything as there are just too many different matchups. If you don't think you can win lane endure it with some more defensive itemization. There is of course other things to work on, map awareness, champion mechanics, positional skills, wave management and you might want to brush up on refining your CS skills as your cs seems low for many of your games.
