Depression sets in when one feels they have no options.
It's a form of shortsightedness to feel that what is happening in our life today means the rest of our life is going to be the same way.
We give up hope whenever we discount the possibility of a better future. Feeling depressed is about the pain one feels in the moment. It also can be tied to their lack of desire/energy to move on, start over/anew, or change. In order to move on you have to let go.
Depressed people tend to keep replaying the events over and over.
Everyone throws a "pity party" now and then but eventually the music stops. Eventually anger or pride leads one to prove no one or nothing can hold them down. Sometimes it's just a matter of reconnecting with positivity and a spirituality sense that lifts them out of the abyss to try something new. Avoiding "negative self-talk" is a fulltime job.
Motivational speaker Les Brown once asked the following question:
How do you eat an elephant? The answer was: "One bite at a time."
Oftentimes what paralyzes and discourages us is looking at our challenge in it's completeness. Setting "mini goals" such as sending out 5 resumes a day, making x number of calls, attending one networking meeting a month, spending a couple of hours per day researching companies or people who might be able to assist, choose to associate with people who are living out their dreams, or read biographies of those who did, create a dream board, use daily affirmations, meditations, and visualization to lift your spirits.
Squeeze in a fun activity you enjoy over every weekend even if it's only walking along the beach while listening to music from your iPod.
Having structure usually leads to having focus which leads to victory.
