If your mental health is bad, you can't enjoy anything?

It becomes incredibly hard to escape. Instead of enjoying things, you end up overthinking. I was watching the anime Monthly Girls' Nozaki-kun, but because my mental health is in such a bad state, I couldn’t enjoy it like a normal person. I dropped it. Escaping reality feels almost impossible. You started becoming more anxious, frustrated, stressed. Your hobbies, relationships, friends everything is destroyed because of your bad mental health. You can't feel anything.
