I'm sorry about your daughter. It sounds like you have thought about your decisions and think it's the best idea. That should be good enough. Although, I know it's difficult when others are trying to chime in with what you are doing and what you should do.
I think it's great you are focusing on you. It can be difficult while raising kids to forget what you like to do. Utilize this time and make those positive changes going forward. It's a marathon not a sprint:-)
