MD Anderson has a wonderful reputation, and you are really heading into a facility that is renowned in the ability fight this most dreadful beast, so please try to keep positive. I personally have not had the experience you are are now undertaking, but know of people who have, and know it can be tremendously frustrating and frightening. There are places online where you can share, unfortunately, the guidelines here are so strict they prohibit posting the names and addresses of those sites here.
I did want to wish you the best and urge you to be positive. There continues to be many encouraging people and survivors out there to take inspiration from!
