What do i do... Lost

Today my best friend lost her sister to heart failure. Just a year ago she lost her mother to cancer. I'm far from home and I'm very sad that I can't be there to comfort her. I had just recently had a baby and traveling doesn't seem like it's gonna happen. I'm at lost for words and the pain she must be in. I don't know what to say to her, I'm sure she is very sensitive at this very moment. She has not contacted me and I don't want to call just yet, I'm sure she is with her family right now. Im so lost... 😢
