I need your help.

So lately I've really enjoyed climbing the silver ladder. Despite the horrible attitude and conutless afk:ers, I've survived through the divisions but now I've reached a dead end... I started of this season at bronze 1, but quickly I managed to get back into silver. I got into a real flow and managed to climb through silver with my beloved , reaching a plateau here at silver 1. Idk what to do, never in my life have I experienced this many people who wishes cancer upon you, people who AFK because things doesn't go their way the first 5 min, or that ends up dying a 7th time against the enemy Zed in the middle of the lane and blames the jungler because the didn't win them their lane. I need help. The last 3 games, my mid laners have gone, 2/8, 7/14 etc. I can't remember the last time one of my solo laners actually won lane or at least went even. Am I just unlucky, do I need to roam mid more, I'm stuck.

Ik it will be hard to give advice since improving is different to everyone but this stop came really sudden and the climate here in s1 is something I've yet to experienced. I'd really like some genuine tips on how you managed to make your way through this and possible tips for support mains. Or the usual "git gud" and "u can't climb as supp"... That will work too lol.
