I kinda know how you feel, except I had a friend before I moved out who was online on here, and we lived in different countries. When I moved, I'd barely be able to get to a computer because of the internet, we have none at our trailer. She got mad at me one day, accusing me I was ignoring her, yet I told her repeatedly my lack of internet problem and job (at the time), so it couldn't be helped. She ended our friendship. I only took it lightly because it was online friendship. I'm here to chat occasionally, be friends to have people to talk to/share ideas with, but unless we have soooo much in common talk/text on a regular basis, I keep things light so I don't get hurt. Online relationships can at times just not work out for miscommunication reasons and therefore, you shouldn't worry. She chose to end it because she wasn't understanding enough for something you couldn't help. She's not a real friend to begin with.
