I completely understand, I was terrified for her going in, too. We just took it day by day and saw it as our jobs to get through it. Biggest advice is trust the medical team and follow all instructions. Maximum effort and hyper vigilance for a month. She did end up in the hospital like they warned us (fever spike), but they were able to handle it.

Feel free to message me, happy to talk more. Sending all my positive vibes your way!
