i need advice guys

i went from bronze 5 right up to silver 4 in a few weeks. maybe a month and a half. it was soft competition

then i get to silver 4. and recently. problems have been unbearable, i have studied all the tactics as a mid laner, i main one or 2 champs, mainly one, cassiopia. and when shes picked or ban, twisted fate,

heres my problem. my goal at the start is, farm farm farm, poke, amd try get a kill or 2. sometimes even getting 3 kills, then we reach the 10 minute stage, botlane has fed maybe 6 deaths, support went afk because adc has 5 of the 6 deaths,. toplane has fed 4 deaths, jungler is freaking out in corner sitting down, rocking back and forth because it doesnt know what to do with 2 lanes screaming at him to gank , ganking either lane is unwinable and hes underfarmed into the bargain, its like walking into a mental hospital where you see people with bins on there heads and dancing around using toilet tissue as a flag, as i speak, adc is argguing with support because support was autofilled and wanted adc, but adc wont give him adc, so he basically has said "ok i troll" so this is game loss gaurenteed,

and this problem has persisted the past 3 days leading to a HUGE uncarryable losing streak. im a big fan of, try not to die , and get fed , but its impossible not to die when veiger goes 12-1 vs an aatrox in toplane, and nautilas is jumping on your face for the veiger to 1shot u, despite the fact you MOPPED the floor with viktor in your lane going 8 - 1 in ten mins. (botlane fed that game also and jungle was 4 levels behind due to a ping problem)

so now you see, when i say huge losing streak, guys were talking 14 games maybe.

2 games ago, i got paired with bronze 4 adc, whos history had 0 games with positive scores , and his clan friend, who was playing top lane even tho he mains support, he also had negative scores all round the board, both fed like dogs and the toplaner was bronze 5,

im silver 5, i know its not spectacular but these guys are still in nappys with league, why are they on my team ?!?

my point is, how do players avoid these things from happening every game, or is tehre something going on in the league community or client that is leading to mix ups in the matchmaking / players having ping problems., whats going on. i cant get demoted back to bronze if i do, i ll quit. and im on the fkn border guys!

i rarely posts rants about not being able to carry and tbh if it was a straight up 5v5 each game going to mid or late game and losing , i wouldnt mind, but its not, its afks, pingers, and feeders in both top and bottom, and i cant stand or understand it.

im not in the process of working on my own kda , only giving one death and only taking kills when its safe, and farming alot, so that i can prove to myself that its NOT me feeding and losing these games, its just so hard to do that even , when your team gave them so much that anyone can one shot you, sometimes even the support brand can blow me up he gets fed so much.

all adc can say is "ye mate, build mr, idk how hes so stronk"

im like, " bud you gave him 11 kills in 7 minutes, hes not even farming cs, hes farming you"
