hello, one of my accounts is gold 3 its a solo q only account I won 10 games in a row then started getting into ascendant 2-3 players in my lobbies, then the next game bronze 1-3?

A year ago I sold my pc, was downsizing homes, BUT WERE FUCKING BACK BABY! Anyways, I suck, like bad, I used to top dfrag, or be positive in ranked, I still understand mechanics, played cs for 5+ years. Am I just old and washed like the 13...
