I got significantly worse recently and i dont know what to do.

2 months ago i got up to 1420 elo. I was even feeling like i could reach 1500 possibly. I was beating 1300s with ease.

Now i started loosing and i dropped to 1200 and have to sweat my ass off to beat a 1300.

I just can't get back up to 1300, no matter what civ or strat i go for.

Has this happened to anybody else? Getting worse and not being able to recover?

Im not talking about hitting a plateau, im saying getting worse unexplicably.
