Support in ranked

I loved support while leveling up, but now I hate it. I believe that I can preform to par for my MMR in any lane. When I play ranked, sometimes I get support, and sometimes I don't. I can say with confidence, if I get forced to support in a ranked game, in all likelihood, I will lose. Every time I play support in a ranked, the game goes a little something like this:

gets caught out before the game starts and feeds the enemy

gets hooked by and trades deaths while I, , finish off for the first kill on my team

comes and tries to gank but gets hooked and has to leave

comes to gank and kills , while I remain alive to get the killing blow on

sucks ass at CS, while feeds the enemy

While I'm back at base, stays and gets caught out

tries to steal drag while invisible but messes the timing of the smite up

We lose mid and top towers and then 5 bot and and die; bottom tower lost

steals drag with random ult, then everybody comes to drag and feeds while I back

<lots team fight losses here>

repeatedly gets caught out way on the other side of the map while we turtle

Enemy team gets baron, we lose our inhibitors, GG.

EVERY TIME I SUPPORT. EVERY TIME. SUPPORT GETS ME CHAT BAN EVERY TIME.
