Need help.

I don't know what to do anymore. In my match history, I have 7 loses in solo 6 of them there were 20+ deaths split between 2-3 of my "teammates". How am I supposed to carry that when I rarely have someone else to help me out? I haven't playing as much simply because of the this crap. "Teammates" feed and either I roam and try to help them causing to lose mid or I sit in mid and end up losing anyway due to there not being any pressure anywhere else on the map. I don't know how I'm supposed to do anything in a team fight without at least 1-2 other useful teammates especially when my already feeding team starts the fight being behind in both gold and exp.

Silver was not this damn hard last season (made it to gold and quit playing soloQ, last season) and feels worse than bronze ever did for me.

I switch between adc and mid when I find one to be too toxic to play aka the current state of bot lane

Any help would be nice.
