Yes, it passes, but often takes longer than our tolerance level can bear. Puberty age girls are like aliens from another planet, but it upsets them too.
Whoever tells their daughter that their puberty and all that comes with it, is the wonderful part of becoming a woman...ought to have their tongue ripped out. Nothing wonderful about it.
Hang in there mama, find your own space for when you need it and encourage her to talk about it when she can manage to sit still for a half hour.
