Worst S7 experience.

I haven't had such worse start in any other season with my main. I'm 4 wins and 16 losses in after placements on my main account and I can't seem to break that losing streak. Is my main screwed? I really wanna get far with my main too but the thing is that I don't seem to break that curse right now. I don't wanna blame anyone. I just happen to get lots of bad games somehow and it's slowly getting irritating (people who troll and are generally toxic or don't play well). Is it worth continuing on my main or should I move back to my smurf and try my luck there?
