Is it a sign?

Within days of giving notice at my job I started to experience a "bad patch". I'd had an unexplained lump on my jaw - just south of my right ear - for a couple weeks. My GP thought it was swollen glands from a virus. When it got worse over the week following this diagnosis, he decided it was probably TMJ. I asked to see a specialist who took a fine needle biopsy. I had to wait a week to see what sort of cells were populating the lump. Waiting to hear if the lump was something other than a malignant cancer was not pleasant. Then my doctor finally called to say the test was inconclusive because the culture had failed to grow. Now he wanted a CT scan. Fine. But I had to have a blood test first to make sure I didn't have too much or too little of something in my blood that could cause problems when combined with the dye they planned to inject to create "contrast" on the scan. Crap. The whole business was getting tedious. The next day I ran a quick errand to Whole Foods. While exiting the parking lot my car died. I was blocking at least nine cars. Later, after getting my car towed to the shop, I borrowed my husband's car to do some grocery shopping. When I got home with a trunk full of food I discovered I had locked myself out of the house. That night I had to unplug my computer from our home network when it got a virus that, among other nasty things, replaced all my Internet bookmarks with bogus sites. The only good news is our computer guy came over that very evening and took it away for tests. So here's my question; should I reconsider making major changes in my life?
