take a break from chess, enjoy your time away, and then come back and play some games.
remember that chess is a mental game and if you are frustrated, tired, distracted, etc you will play worse. Also chess is suppose to be fun, if you arent having fun then it might be best to stop playing.
Recently I got to 1475 rapid but I've lost almost every game since 3 days ago. I used to be better at chess and I can't keep losing. I study tactics and endgames but I'm getting worse and worse.
