Can I vent?

It seems that there is always something for me to be stressing about. When we first moved here I stressed about getting a teaching job. Then I got a teaching job and stressed about how to be a good teacher and keep on top of things. I am feeling much more comfortable in that area. Now within the last week both of our cars are having issues and Roy has still not found a job for the semester . Oh and I have had some kind of sinus cold for the last month that will not go away. Why does it seem that when one thing goes wrong everything else seems to go with it. Is there ever going to be a point in my life where things work out and I (little miss worry wort) won't stress?
