With the behavior of eating less, we discussed how depression inhibits a person's ability to find pleasure in the things he or she once enjoyed. The behavior on this page can also be a casualty of that symptom. As a depressed person stops socializing and participating in activities he or she once liked, he or she can have less interaction with loved ones.
The problem with this behavior is that it leads to isolation, and isolation can increase feelings of depression [source: Schoevers, et. al]. To avoid the cycle of chronic depression that can be caused by avoiding others, it's important for someone with depression to not only seek treatment, but to also rejoin some of the activities he or she once took part in.
