I don't understand, why me?

I never knew that I had this feeling. If I'm going to be honest I hate this feeling. I hate to feel like this. I never want to feel like this anymore, it hurts in my heart knowing that this will never end. Knowing that I'm going through this agine. I can't deal with it anymore, I have no power left. I don't know what to do. Why doesn't anyone help me, tell me what to do?
