I'm so sorry to hear this.

My chapter has been there and done that - the year I was a rho chi, I was heartbroken to be the first AEPhi to hear that quota was 32 and we were only extending one bid... I kept thinking, if only someone else had been a PX in my stead, I could have brought at least one more person in.

But the woman who joined us through FR was and is a great sister, and we COB'd our hearts out and got some more fantastic new members that year.
Take some time, do some sisterhood fun stuff, relax and regroup. Then, hit the ground running for COB.
Good luck!
