Yes. Your rating is not some unimpeachable arbiter of your absolute skill level. It's just a reflection of your results over a period of time. Improbable things happen every day, and the Glicko formula doesn't know whether you lost a bunch of games in a row because you were playing beyond your true skill level, or whether you were sick, or preoccupied by what you were going to wear for date night, or whether your opponents steamrolled you because they lucked into some crucial moves by accident, or some combination of all of these things.
At the end of the day, it's just a number. It doesn't mean anything. You're not suddenly a worse player because your rating dropped. Odds are, it'll come back up, and in the meantime, enjoy the easier competition for awhile.
Ugh, my elo rating dropped 200 points over one day. It went from 1120 to 913. Has anything like this ever happened to anyone else, it makes me feel so frustrated, wanting to quit, and just like I'm failing at something. I hate how I keep missing things I'd easily pick up on in the past.
