I'm getting so tired of boosting

I cannot gain ELO anymore as a solo player. I don't make friends and I cannot use skype. So I play solo. three games in a row I've had to fight smurfs/boosters. I know they are b/c they go like 10/0 in lane, despite me going 5/0 in lane. I go top they go ADC mostly and late game they just completely outplay my whole team.

Just went against a Vayne, has 30 games and is Silver 3. This Vayne would save her ulti only if I was near (I was olaf). Thresh and Vayne always positioned perfectly to counter me while my team was trying to kill Malphite. No one got her, no one did anything but focus Malphite. Impossible to kill when you're trying to kill diamonds solo in Silver.

Before that I had to fight a Yasuo, got 2 kills on mid, went top killed me, killed everyone. Game was completely out of control.

I haven't felt like I had a 50/50 shot of winning a game in so long. Either I get no smurfs and just smash the other team, or I get smurfs and get smashed. It's hardly ever a good game.

Most times I look at the games and think to myself, there's nothing I could have done. Even talking to the few plat people I've met who offered to boost me b/c they saw I was decent. I won't accept it b/c I want to prove to myself how good I am.

TDLR: There is no 50/50 chance of winning in most games. Either smashed my smurfs/boosters or smash with them.
