If you are experiencing depression, you will react as if the whole world is crumbling down in front of you with no foresight of redemption. In most cases, you will also tend to think and act irrationally. It puts a strain on you, preventing you to see the better side of the goodness of life. It only makes you feel that everything you want to do to make your life a better place to be in, turns out to be a wasted effort.
People closest to you will also feel the brunt of your depression. They want to help you but you may not see their help in a better light, and you may shun any form of assistance from them. In the end, they will not blame you for leaving if it is going to make things easier for you.

There may be many reasons such as one losing a job, or experiencing failure due to occurrence of an event. Even though you are in a strong relationship, this feeling of depression can snowball and have an adverse effect on your relationship.
