Hey Beth,
Sorry to hear that you are feeling pretty down. We all know that this battle is just as much an emotional roller coaster as it is physical. I agree with Cindy that there is no need to post - but come on and read the funny's. Keep everyone up to date on your progress. If you need support from others - ask for it.
First and foremost, be good to yourself. When you feel like crap - do something special for yourself (take a hot bath, eat an ice cream cone, snuggle up with your children/pet, call someone you haven't talk to for a long time. Take the time you need for your emotional health too. Sometimes a good cry is just what the doctor ordered.
Take care of yourself - I will be thinking about you whether you post or not.
Cheers to better health!
Wendy
