Support LF help

Hey guys!

I'm a bronze 2 support main, I fell from silver 4. I'm having trouble climbing the solo Que ladder due to trolls and some mistakes made on my part (I'm not vain enough to say I'm not making mistakes cause if I wasn't I'd be in a higher rank/Elo). I'm looking for either a team willing to take me on and get better together or a plat+ player that is willing to work with me and help me get better at my role.

Thanks in advance :)
