Balancing work life and mental health?

I recently graduated high school, so Im trying to ease my way into adulthood without too many mental health bumps.. graduating has been pretty hard for me in all honesty. Ive been going through a lot of extremely depressive and anxious episodes with all the plans about college, friends leaving, breakups, etc, so while I DO want to try getting my first job, Im nervous about how to handle it. Does anyone have any tips?
