Yours builds aint that bad, they are the meta, so that aint a problem.
You also farm nice, thats more farm than I expect from a silver player.
The problem aint the teams, cause trust me I found some shitty ones in low elo and I still can carry them.
Probably my advise is to play something "bigger", try to go annie support, zed/fizz/lb/lee mid, shen/renek/nasus(2stronk)/teemo(easy to carry low elos)
I can't say about your game style cause I never saw you playing.
Also don't rage, this is a key to win games, if a teammate does poorly, encourage them to do better next time instead calling "****** u noob".
Make decisions, if you're jungling in low elo and they got a eve for example, she will ALWAYS start blue cause she is mana hungry, so tyr to steal their red quickly then your blue then your red.
Also buy wards, you may be adc/tank/mid get wards, this new season need to everyone ward.
My last advise is to hear some chilling music, like Mozart or Chopin perhaps?
Good luck
