I've been fortunate that my BCG maintenance treatment finishes 2 weeks before Christmas. This in one hand, allows me to enjoy the holidays, but there is a little cloud over head, as I have a cystoscopy scheduled for the end of January. So my tips for dealing with the holidays when you have a cloud over head is to try and do something for someone else less fortunate than yourself. It really can bring perspective to your own issues. I also push myself to get out and enjoy the Christmas entertainment, even if its just going out to see the lights. At best, I try not to isolate and surround myself with family and friends that like to enjoy and celebrate the festive season and one thing I tend not to do is watch any movie that will bring out the sadness in me. Outside of these things I talk to my wife if I'm not feeling good, rather than keeping it myself. A little pact we forged after I was first diagnosed and it works!
