Fair wheather friends?

I belong to a church that is normally very supportive in crises. I announce during prayer time, that my sister was diagonsed with2 brains tumors. Our pastor & his wife are not the best support. His wife knew nothing of this and he told her when he got home. I expected to hug me as this is a traditon in our church,. instead, she brushed me off like I wasnt even there as did the pastor I was so hurt by this Howuncaring and insensitve can you be? When her sister was diagnosed with pancreatitis everyone went up to her and offerred their concers, folowed with a hug. It's supposed to be a normal thing chrch To make matters worse, those I thougt were really good freinds. did the same. NOT a word why don't even care she has 6 mo-2rs to live I'mdepressed over this Can you give some advice on this. I feel so betrayed. Like I don't count. Any advice on how to handle this. Right now, i hate them for this.
