I've been through 10 of these from the complete list which is here. I should probably be more stressed out!
1. The death of a spouse, relative, or friend.
2. Going to jail.
3. A natural disaster or a fire damaging your house.
4. Getting diagnosed with a serious illness.
5. Being fired.
6. Getting separated or divorced.
7. Being a victim of identity theft.
8. Unexpected money problems.
9. Starting a new job.
10. Planning a wedding.
BTW, losing your phone narrowly edged past terrorist threats on the list!
