First, congratulations on getting to the finish line. Today is going to be a day you will most likely remember and be one of your "cancerversaries" There have been others that have talked about that lately. For me, I didn't feel that way, I was glad to be done, and never looked back. Have a fun day with it, maybe you'll get to "ring the bell". Take a picture and post it if you do!
Wishing you the best last treatment ever.
