Here are some common examples of stressors:
1) Graduating High school. Graduating can be very stressful, during that last year of high school. Seniors may start to feel stressed due to: Applications, moving, getting ready to be on their own.
2) Moving. Moving is very stressful, due to having to pack and say goodbye to your friends and family.
3) Loosing a job. Loosing a job can be very stressful. Due to not being able to provide for whom you love because you don't have a stable job and money.
These are some of the few known stressors.
I hope this helps! :)
