In life we get depressed and dejected. That's pretty normal because we humans experience the full spectrum of emotions that's why we are Higher Intelligence! Imagine boyfriend or girlfriend tells you it is all over, you feel you want to cry and die. That is very strong emotion detachment.
I did experience that a few years ago and I can tell you it is really something unpleasant that makes you want to hide in your room and cry for days! So if you are experience such thing now, the key is not to focus on the negatives, but focus on the positives. I'm sure you can figure that out. There are always 2 sides of a coin. One good one bad.
When it seems that life is coming at you in every direction, stop and declare firmly that you are walking in perfect peace. Take back your joy, reclaim your victory, and let the enemy know that you have been broken but you are strong enough to know that you are not defeated. Take control of that very thing. You may have been broken but you are not weak!
