personally I think you should visit her, if she is a true friend she wouldn't take it out on you. If you're scared of going there, ask someone to come with you or write her a letter. Say you didn't want to go so far and that you feel sorry for her. Be honnest, show you're there for her and I'm certain she will apriciate that.
good luck and keep in touch if you like :)

Maybe you could write her a letter? Lily
