No one is useless. They may not be very active or might be lying low til they are able to sort things out, but you are not useless and saying you are useless only re-affirms your feeling of worthlessness and anyone who looks to you for support might as well believe they are useless too shouldnt they? After all, if it could happen to you, it could happen to them too, right?

Using songs to describe your feelings when the words wont come is a common habit of people who cant express themselves but you should remember that music is a creative object and contains much fiction. Music asks us to imagine the way the song writer felt or what the song writer imagined. It is not our own personal truth but it might in some ways fit the way we feel. If you are going to use music as a coping tool, you might want to include something positive and uplifting also.
