Probably just the "one more game" syndrome.
I don't play a ton of live but have had that happen trying to get my rating back up to a certain point. I'll be playing poorly, then win a couple of games. Decide to play one more to get where I want to be, lose, then go on another losing streak. Finally just have to step away.
Take a break and come back when you are less distracted. You'll probably gain most of the rating back.
So, just 2 days ago, I attained a peak blitz rating of 2030. Suddenly, my play started to get worse and worse (I just began blundering real hard even in winning positions). I have been somewhat depressed because of some family problems (which I don't want to talk about in this post), so that's most probably the reason why my mind has not been clear enough to play speed chess. However, why would I drop this many points very quickly? It just doesn't make sense. I have been trying hard to get it above 1900 (and I thought I would easily be able to do it). It feels like I fell into a pit that's really hard to climb out of. It seems like all the progress that I made just got reversed magically WITHIN 2 DAYS. What is going on? I know that being psychologically down can impact how you play, but WHY THIS MANY POINTS? I am literally ~200 points below my peak.
