You may be at a point where you want to discuss your options with a trained psychiatrist or psych doc.

You said:
"I don't have to sleep or eat anymore. I am seeing hallucinations, but they aren't terrible. I feel like I am on top of the world and that I can even fly if I jump out of a window. Why does everyone want to stop such wonderful feelings?"

The reason they want to stop you is they don't want to see you do yourself harm. People cannot fly if they jump out the window. They can get seriously hurt.

No one is invincible. That is a hard lesson to learn. Please see a professional or ask to enter a professional facility that can bring you a little closer to being grounded in yourself.
