Patience is a virtue in what exactly?

I've been taught that patience is a virtue and for the most part I am an extremely patient person. However, my patience is quickly coming to an end. I waited for over two years...yes that's right two years to see a developmental pediatrician. All he did was review his medical chart, weigh him, took his height, asked him some questions and said "yes, there is a problem." I am referred to a geneticist who in turn tells me that she feels that he has Floating Harbor Syndrome and wants to run a series of tests. I don't have a problem with any of that but what I do have a problem with is that every single test has at least a six month or more waiting list. By the time my husband and I find out exactly what our son has he will be driving!!!! I am just frustrated that the medical community feels that we have all the time in world and that we all are on their time schedule. The longer we wait for these tests, the more behind our son gets with his education! Who were the people that taught those doctors to read, write and do math...TEACHERS! I guarantee that if it was their child they would not be placed on waiting lists...they would have immediate access to care!
