Diamoness, I'm so sorry to hear about your miscarriage and your tumor. Girl, don't even worry about the hair. It will come back. I'm sure your tumor is benign and nothing to worry about. Please keep your hair care family posted on your health, and I'm throwing MANY MANY hugs your way. Thinking positive thoughts will help you through your recovery.
I think BronxDiva sports a Halle-like haircut. Send her a page or a PM, and maybe she can give you some suggestions.
Congrats on getting into your top choice grad school!!!
