Dealing with Stress, Anxiety, and Depression
While this is by no means a comprehensive and complete explanation of the differences between stress, anxiety, and depression, it does give you some idea of how they relate.
Stress is usually a precursor to anxiety, and anxiety is usually a precursor to depression.
What that means is that if you are under stress, if you don’t find ways to release the feelings of stress after the event has passed or learn techniques to cope when under stress, then that underlying worry you carry around with you is likely to be ingrained as anxiety. And then if you suffer from constant anxiety for too long, chances are that you could slip into depression a lot easier. And this often becomes a vicious cycle that is hard to drag yourself out of.
