II wonder what do you think about this problem?

My sister is a good sister. She lives in N.Y. She has a two story house in the beach in Puerto Rico. I had been sick quite a while and I live alone. I had so many medical problem, broken discs (6) I had a heart attack 4 months ago and I don't have to many people to talk to since most of them live far. When my sister is in N.Y. she calls me more often, (she always saying the same thing anyway.) When she goes to the Caribbean I call her and she does nothing but complaints. The thing is that she always cut me off for several reasons, sometimes she says, I have to go because my feet hurt, because is windy outside on and on. I get upset because I'm the one who's paying for the call. I get to the point that I decided not to call her anymore. I was thinking to visit her and she told this afternoon if anybody wants to go there they have to do their own things because she is not going to be carrying people around. This disturbed me because I'm not expecting anybody taking me around. Is a long story but I'm fed up and I'm thinking to cancel the trip. I went there about two years ago and we went to visit some friends and I could not say a word because she monopolize the conversation. The fact is that she goes over there 4 times a year and she can talks to all her friends who are my friend also. The last time we went to visit my cousin who is dentist and I want to ask him a question and she took over the conversation and the only thing I could say was bye, it was nice to seeing you. Thank you to all of you.

(Sorry if I put this in the wrong category)
