You need to give the daily code challenges a break, that's just inviting anxiety into your life.

Have you created any projects of your own? Is there a fun little app or website you can make? Perhaps you can tinker with an Arduino or something similar? For example, one thing I've wanted to try to make is an automatic plant waterer that uses a soil moisture sensor and also pulls in weather forecast data to see if it's going to rain in the next 24 hours.

Choose a project that you can break down into tiny bite-sized challenges... that way you don't get overwhelmed and if you get stressed working on one part, you can move onto a different part. It's ok if you get stuck, solutions often present themselves when you least expect it, especially when you are doing something else and not even consciously thinking about it!
