"Are you okay?"
‘I don't know.
I don't feel okay. I feel broken and empty. There's nothing there. I don't feel anything. I don't know if I'm okay or not.
How can I?
I'm anxious all the time for no reason. Tired. Alone. Desperate. I don't know what I'm desperate for, I just don't know.
So to answer your question yes, I'm okay
