I'm sorry you had to join the b/c club. I'm there, too--in fact, I've been initiated twice. I read your journey and see you have both chemo and radiation coming up. I've had both--and I survived both. I agree that the waiting for chemo to start can be tortuous--but in the meantime, why not get ready for that first day by packing a chemo bag with everything you may want during chemo--some snacks, crossword puzzles, ipod, and comforter or quilt. I left mine in the hall closet and each chemo session, I'd just pull it out & it was ready to go. Plan what clothes you'll wear. Do you have a port? If so, plan to wear clothing so that your port is easily accessible to the nurses. Most people who've had both chemo and rads say that chemo is worse, and I agree. But this way, you will get done with the worst part first! That's GOOD.
Radiation wasn't too bad for me. I didn't burn--some women don't--and really, going to get the radiation every weekday for 7 weeks was much more bothersome than the radiation treatment itself! Enlist the help of friends & family to take you to chemo and rads. I have been very open about my cancer and have found I have friends who have a curiosity about it. They've taken me to radiation & chemo and thus will be much better informed when cancer happens to someone they know.
I don't know anything about expanders, since I'm planning on a DIEP flap recon in October. But if I can hold your hand through the computer or reassure you about chemo or radiation in any other way, don't hesitate to write to me. Good luck. We ALL care about you.
