I Don'T Know Where To Put This

I have two sisters, both younger than me (22 and 21) and I have drifted away from both of them. One of them ran away to America and married an elderly man without anyone knowing. She has her new life and barely talks to me. When she does, she's angry because apparently I've not included her in something or done something wrong.Basically whenever she contacts me, it's to shout at me.

My other sister doesn't seem to be bothered anymore. I try and talk to her like I used to, but I am regularly ignored. Something really bad happened to me yesterday, I sent her a message about it and got "sorry, I was at work" and then a change of subject. She's going away to stay with my other sister for a month and I feel like that might be the end. We were all so close as children, teenagers and young adults, so it's just sad.
