What is my problem

My body hurts so much. I don't know why or what has changed. It is a horrible feeling.I ache from head to toe.

Also, I have been so cranky lately. People I usually love are bothering me. People that I never see but for some reason I have this crankiness in my heart towards them and I don't know why.

I snapped at a guy at the gym. He was this older black man who was staring at my body when I got in the jacuzzi. I said,"Can't you stop looking at me"? He said, "huh"? and I said," CAN YOU STOP LOOKING AT ME". I then sat in the jacuzzi and tried to act normal but I felt really dumb. When I got out I apologized but he was still staring at my chest. I wanted to tell him to stop looking at me again.

I don't know what my problem is but I hate everything right now.
