i really do not think anyone really understands unless you've been thru it.
i knew of people who had done IVF and i never understood it, the emotions, the pain, and how hard it was to get pregnant.
the thing is if it wasn't for BB i think i would feel that no one really understands.
we have some friend who have been lttc for 3 years and announced preg when i had my last BFN. it was so very hard for me to be happy for her and i avoided her like the plague, only recently congratulating her.

be strong, and remember you've got your BB friends. kisses and hugs
