What should I do if I feel mostly empty and I feel pretty fine with it?
Can you explain what you mean by feeling empty?
First of all I feel empty in my head. Like most days I don't think about anything and I don't have any problems.
If your mental state is startling to you then you might want to seek out psychotherapy so that you can get a better understanding of why you might be feeling that way. It's makes sense that feeling empty might be startling.
No one should be making fun of my mental health.
If you feel fine with having little to no thoughts then it is fine. You should only be concerned with persistent negative thoughts.
