That is absolutely terrible news. I feel bad for her that she felt the need to lie about it to friends, depriving herself of an additional support structure to help her go through such a hard time. I'm glad she finally came out with it though, as keeping it a secret probably wasn't doing her emotional state any favors. It's debatable whether the world needed to know, but I suppose we all would've found out anyway eventually.
Truthfully, I'm not sure she needs to start a "foundation" over it though. I mean, that's probably the knee jerk reaction to what has happened. I will say though that the part about miscarriages being "a bigger club than people think" is absolutely true.
In hindsight, I can't believe she came out after such a tragic thing and performed the way she did at the Royal Rumble. I mean that in the most positive way imaginable. That speaks volumes about what kind of professional, what kind of wrestler she truly is.
I can't wait to see her back full time, but she needs to take sufficient time to deal with the situation the best way possible. God bless her.
