What do you mean by this?

"Seeing this happening with my very own eyes makes me feel hopeless and useless. It breaks my heart because I could not do anything about it and even doctors as well. Out of all the people of this earth, why on someone who is truly good and pure in heart. Being the one who is about to leave is hard but being the one who is going to watch that person leave is harder especially when all you could ever do is to accept, understand and Trust His Heart. God help us."

Do you really mean that you are already leaving me?
You posted this one last night and I don't know what you mean.
Are you leaving me already?
I'm sad but I won't give up.
