You asked if she is okay...that is all you can do. I wouldn't push for answers...just leave her be. If she wants to talk to you, be open and just listen...offer no advice unless she asks for it.
She is in so much pain within that it's difficult for her to maintain the mask of happiness all of the time. She is very confused and doesn't know which way to turn. She will need to work this out for herself. My xh was very similar in the crying mode for a bit and once he got over that little hurdle he was h@ll bent on enjoying life as a teenager once again.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
