Can you help me with a few phrases?

I'm writing an abuse fiction and I need the following in pinyin because I am not sure of my own Mandarin at the moment:

"You are hurting me."

"I want to die."

"I hate you."

"You are my friend?"
(I thought it would be "Ni shi wo de peng you ma?")

"I am hungry/I am always hungry."

"Those are my things."

I also need titles (hope this isn't too much):

Sir
Miss
Master (as in, young master)
