Nosy?

I have a person in my life, someone I have known from the beginning, who wants to know every detail of my life and wants me to talk about deep personal things every time I see them. And usually when I see them, it is a day that is not a day I want to think about deep personal issues. It is a day of celebration or good family time. But they don't get it and I am not able to tell them in a way that is not hurtful. It makes me want to not talk to them at all. I don't want to be asked the questions I don't want to answer. It was recently pointed out to me during one of these incidents by a third party, that all this person was really looking for was a good story about vacation or something to help gauge how the trip really was. But I was incapable of understanding it. I am incapable of saying, I had a good time on vacation, because all the great stuff is tainted now. Its just the way it is. And having to relive these things on demand is too much for me to handle, so I avoid it all together. The thing I try to do most is not think, not feel. Its quite exhausting. There is this very powerful river flowing deep below in my emotional state. I can only stick my toe in every now and then, because it is just too powerful. I am not only afraid it will whisk me away and I may never come back, but I am also afraid it will drown me. It is just too painful. I don't want to dip into it at all. And I think its unfair for people to assume that I want to just so they can feel better about themselves. So they can rest their minds that they asked and that everything is wrapped up in a pretty little package and I will be ok. I will not be ok, not ever. They get to go back to their world where they can occasionally think of me and shake their heads about how sad and tragic it is. I don't get to go anywhere. I have to live here.
