One of the parts of depression is feeling down, insecure, unworthy and a myriad of other bad feelings. Depression can be caused by several different factors and effects millions of people.
The problem with depression is that many people do not practice accountability. Suffering from depression does not automatically mean that you can not live a full and happy life. Do not dwell in the low points.
Conquering depression means finding new habits and practicing constructive behaviors. For example, during manic times some people may feel highly euphoric and then they tend to do destructive things such as binge shopping, gambling, being promiscuous, and things of that nature. Try something to counter the usual acts such as meditation, yoga; something to calm you down.
On the other hand depressive times will lead to depressive behaviors such as isolation and sleeping all of the time. Why not try an aerobics class or an art class; something to get active.
Depression is a real disease that at some point needs to be dealt with with some responsibility. If you see a person with cancer continue to smoke, you think it’s wrong right? What makes this any different?
