Diamond support main desperatly seeking duo help

i was diamond 5 a week ago, and due to very troll teams and feeders and some tilt on my part i am now low plat 2 with a fucked mmr. I had worse luck with teams then i have ever had before. i was on a 12 game winning streak when i got promoted to diamond 5. i then proceeded to go about 10-50 after that due to teams feeding every single game. Im not even joking. Now my mmr is so bad i get even worse teams. I pretty much 1v2 in my lane bottom and win lane every single game, but by the time we take turret my mid top and jungle are all 0/5 or worse and we just get crushed. So i am looking for a very good mid or jungle or adc to duo with and get my MMR back up to where i am supposed to be. I play mainly Naut, janna, nami, alistar and blitzcrank but i can play pretty much any support in the game. Please help me.
