Feeling the crunch

I love my family and goodness knows that I try to be there when they have needed me. Is it just me or does anyone else ever think that maybe your family has just lost their minds? Okay that's where I'm at right now.
I have a situation with my father and siblings that appears to have no resolve. So exactly what do I do now?
My father is 83 and in fairly good health, but we never know when that dreadful day will come when we loose one of us. It haunts me everyday knowing that I am not allowed to speak with him. You can say that after two years of this craziness I'm feeling the crunch.
I pray everyday for my family, my 2 sisters and 2 brothers that won't speak to me. Somehow one sister got control over the entire family and is calling the shots. How in the world did we end up here?
What do I do when I've tried everything to work this out to no avail. There is nothing that I can offer to make things better, for the one person who started all of this has determined that I am not worthy enough to have any contact even with my aging father.
Time passes us by very quickly and no time that passes can ever be recovered. I am lost as to what to do now that I feel the crunch of time slipping away. As much as I have tried to repair whatever the damage that I have been blamed for, one person, my sister,  won't let it go.
I feel the crunch everyday and it hurts my soul to think that I might lose my father without even seeing him again. How do we get around this?
I long to see my family, but not even I am willing to be pushed around by someone who can't apologize to a child for something that was done wrong to them.
Is this my burden to bear? Perhaps so since I have been pushed aside and have been warn to stay away.
Sometimes feeling the crunch of a situation that burdens our soul with sadness is just the way of life.
I suppose all I can do is to keep praying and believing that all will end well.
Perhaps at some point someone else will feel the crunch enough to let go, let God.
Perhaps........
