Chess tilt from 1398 to 1260, too much blitz?

I’ve gotten back into chess for about a month or two now, i played alot of rapid and managed to nearly reach 1400 elo, that’s when i stopped rapid and started playing blitz for about a 2 weeks or more, after getting back into rapid, i dropped nearly 150 points of elo, i keep making moves i normally wouldn’t, one-move blunders, its really discouraging dropping that much considering a game lasts almost 20 minutes, those 20 minutes add up and as college student i can’t really put in more time, but at the same time i’d really like to reach 1800 maybe even 2000 one day. does anyone know a reason what caused the tilt and if playing too much blitz has anything to do with it?

Any help would be greatly appreciated 🙏

I had this experience too!

If you can manage even 10–20 minutes a day, here’s a simple study routine:

5–10 min tactics
1 rapid game
5 min review of that game

Thank you guys
