Getting demoted to B1 again soon

Hello folks.I had posted another thread 2 months ago about being unable to climb and people helped me with their responding.However,I realized I can’t keep maining kalista in my Elo at the moment unless I play with a friend,because my supports kept not understanding how my ult and w passive worked even if I told them multiple times.So anyway,I changed mains and now I main Neeko basically.However,my last games have been miserably bad.In ranked.I am not a pro,I deserve to be in silver probably because I Have to improve more.Even though I main mid lane,I never roam because I am too afraid to leave my lane.Even though I ss (I ping the question mark multiple times the moment my enemy steps into the bush),my teammates will say “report mid no ss” and I insist I do ss but they keep saying I don’t and they want me to write ss down.What is the point of the ping then ?I play very safe,until the time we play in team fights,where I start dying by a fed lane .Please don’t say “your game you had 4/8 with that champ or 2/6” .to people who say that to everyone : not everyone feeds in low elo and if u take a look in timeline and scoreboard you can easily see which lane Fed the enemies.For example,my last game I played vs Veigar and we were 0/0 until ten minutes when the other lanes fed the enemies non stop and Veigar kept being 0/0 until we started team fights.If a lane feeds,it is obvious that their teammates will die because of their fed enemy lane sometime in the game.Well I try my best in every ranked but I keep losing for the past few days EVERY ranked in a row.My mmr is so screwed right now,that I am afraid to play ranked again.It seems like every time it’s a loss,cause enemies are fed and can communicate and my teammates just flame eachother and say “stfu I will do what I want HEY ENEMIES WHO WANTS FREE KILLS”.This is why I’m playing safe.I don’t wanna give my enemy first blood or any kill until 20 min.I want the game to go on smoothly.I am thinking about ditching lol in general cause it seems like a dead end.In this post,I don’t say I am a pro,or that I don’t make mistakes.My farm perhaps is bad,I am trying to improve to that and poke the enemy so they lose farm too.I never flame in chat.I try my best.But it seems like people don’t care about winning the game.In normal games,yes I have bad teammates too from time to time,but not in every game,they wont feed in every game,they won’t flame in every game and they won’t troll in every game.Ranked games just ruin my whole day after playing...And I know that you are tired of every noob in low elo complaining about their team,however I try to improve myself and do my best in the game and people tell me that I have to carry stupid people in low elo to climb,but I really can’t when enemies are fed since 10 min...if I do mid is dead.The worst thing of all is that I feel useless,because I am in the same division and have the same mmr with someone who feeds since minute 1 and can’t dodge any ability .Idk what else to do,I am not having fun playing LoL anymore.

Edit : I now try to learn jg so I don’t perform well in normals and my mmr died there too because I did not know there is mmr in normals too and now I get matched with 20-30-40 lvl players
