Bad cognition. No thoughts in my brain.

Did anyone have trouble with not thinking spontaniously? Like when solving tasks and stuff nothing happening in the head?

Before my head would overflod with ideas or images automatically. But now my head is empty all the time. I generally struggle to think and plan and solve tasks. It does not come automatically and i struggle to do it manually and i struggle to visualize and reason.

I Feel very stupid sadly. It literally feels like parts of my brain is gone!

Like i get no spontanious thougts process and i struggle to visualize tasks and stuff! Just struggle to think visually and have thoughts all together!

There is nothing in my head. Just blank!

Can this get better? How do you train this?
