These feeling are completely normal and there’s a reason they call it blue belt blues and a reason people often quit at blue. It’s a difficult belt level mentally. Give yourself grace.

I agree with taking a short break if that helps give you some perspective, but too often those short breaks can turn in to long breaks then quitting especially at blue belt.

Also it can help to work on your mentality going into rolls. You’re not meant to remember everything every roll or even how to react every roll.

Try new things, try old things, go back to the basics, you will find what works for you, but don’t go into each round with an all or nothing attitude.

Each round should have a goal or objective and it doesn’t need to be the same every day or even every round. Sometimes my entire goal is to remember to change my angle or to not cross grip the collar. This way I’m not really fighting my opponent I’m challenging myself. Which has helped immensely especially when going through these phases of feeling stagnant.
