Am I still here?

Here's a Robot that I wanted to make into an Idea I have for a game, but every time I try to work on any I deas that would normally bring me Joy, I am feeling nothing. What's wrong with this stupid brain? why can I not find Joy in the things that I normally find Joy in anymore? All I am finding is Anger and sadness, where do I go from here? How do I get the Joy back? and stop Procrastinating on things and feel less useless?
