Hello everyone! I have encountered a problem — I can't solve problems anymore that I had no problem with earlier.

I began CP in 2023, and was solving grey to cyan problems. In early 2024 I began to solve many blues and 1900s, after that I was just solving contests, and everything went very well, I really enjoyed it.

In late 2024 I decided to solve more hard (for me at the time) problems, and solved many 2000s. And that's when the problem appeared first: for some reason I lost the ability to solve 1200-1500s. I couldn’t understand what was going on, so I decided to solve a whole bunch of 1200-1400s. It didn’t help AT ALL. I began to avoid live contests for the first time.

Later I tried solving harder problems again, up to 2400-2500, and it went fine again. I solve them a bit slowly, but on my own, without or almost without editorials. And I really liked solving them.

But I still can’t solve 1200s… I do solve them, but not during live contests and much more slowly than I used to, a year and a half ago. When I see solutions to the problems I can’t solve, I realize that I’m overcomplicating everything. How can I get rid of it?

Should I give up on 2500s and solve only 1200s until I stop overcomplicating? (That may ruin the fun of CP for me though.) Should I solve 2500s, enjoy it and stop caring? (Kinda hard to not be demotivated by my low ratings, so it’s also ruining the fun. It's no fun to feel stupid.)

The more I can’t solve easy problems, the more I question my abilities, and it just poisons the whole experience..

Has anyone else encountered this problem before? And how did you solve it? Any help will be highly appreciated!
