I guess it would depend on the situation. I have been angry at people who have been nice to me for many reasons.
I don't know what is going on with your situation...
It could be you just don't like the way it feels, you feel you don't deserve it, you think the person is being fake...
There are just so many things it could be.
Hang in there and if you want to talk about it more, you know we are here.
