Looking for support main G1 or up. Read below

I'm a top laner main for the most part, but im trying to get into adc. I have a good adc pool, Lucian, vayne, tristana, and draven and sometimes twitch. Looking for a support who can help me learn the role in more depth. I mained adc in s5 and things have changed since then. Don't expect to que up and win every game i will make mistakes but i will learn from them. Looking forward to being added, discord is highly pref. My strengths would be positioning i know where to stand in a team fight, i just stink at laning. Not sure when and when not to go in, thats why im looking for a support main that knows the ins and outs and can shot call. Farming is also an issue for me, i try to avoid getting harassed so i lose a lot of cs and slowly fall behind. But i know not to fight when i am behind. Any supports is fine i prefer not to have a leona tho lmao they have a tendency to turret dive level 3. Thank you to anyone who reads this, have a wonderful day and good luck in solo que ;)
