Not much. We're just pushing through. Really, just any encouragement and support helps. I also have schooling to do and just... Help helps.
First thing. You did nothing wrong. You can be a good friend by you opening up the conversation if she won't start it by just letting her know (maybe you could phone her) that she has support, and that she can rely on you. If you know where she lives, maybe you should check up on her… I hope she has a full and speedy recovery. רפואה שלמה!
