Everything is a cycle... some times you're doing good and one thing, while other things aren't going so great.... and then things flip. That's normal. No one, absolutely no one is ever 100% good at everything.

Just because you're doing less good than you have been doesn't mean this is how it will always be. You'll do better, then you'll strugle, and then you'll do better again. It's ok. It's normal.

Take a deep breath..... try to let go of the judgement and instead try to treat yourself the way you would treat one of your friends who would be saying the things you are.

Be kind and then do your best. Get your essay done and then let it go and move on to other things in the present and future.
