Sam that's so much of a bugger - I hope you are now on the up from the treatment. I so know what you mean about being over it - some days even when nothing was particularly wrong I would just walk out of the hospital and cry just because I even had to be there in the first place.
As Tonya so wisely says - you cannot possibly be "up" all the time. Authentic emotion is very important - I find sometimes once I have let the anger and sadness out it just isn't there anymore and I can be just focused on now and enjoy it so much more.
I really hope that the energy kicks back in soon.
