I understand what you are saying, but I don't think having POTS is more difficult than cancer in any way. I am very thankful that I don't have a potentially fatal disease, even though POTS makes me miserable on a daily basis. Cancer is normally "quicker" than POTS and there is so much more info on it but I don't have to live in fear everyday that I might be killed by this syndrome or that cancer might come back.
