How to rebuild relationship with my sisters?

I went through a bad break up with a guy 12 years ago.

It left me in a bad way for a few years. My sisters are still mad at me for it.

I'm back to my old self now.

We went on vacation last year and my two sisters were mean to me the whole month we were on vacation. The only time one of them spoke to me was when she called me fat or didn't like what I wore each day. She yelled at me for talking to people in our tour and not her. Got angry cause I spoke to my mum the whole time. How could I talk to her when she kept putting me down. Also kept bringing up what happened all those years ago.

This thing happened before we went on a vacation 12 years ago.

I know it brings up bad memories and they probably haven't gotten over it but I'm trying to fix it but I don't know how.

Any ideas?

Thank you

My sister wants to go on vacation next year and I told her I'd stay at home to avoid another repeat performance of last year. She got mad that I wasn't going. I also can't afford it.
