(((((FBH))))) I am so sorry your daughter is well a teenager!

My little sister is 16 and I get calls all the time telling me she won't live to see 17 if she doesn't get it together. I just laugh and tell my aunt she said the same thing when I lived at home.
Maybe she is worried that she won't remember her combination. Maybe you could let her know that you will write it down and she could call you if she forgets it.
Oh and not to change the subject but Sera got her Valentine yesterday. I am glad it came a few days late, she has pink eye and it really brightened her day!!!
I hope it gets better soon!!!!
