On some level it's true of course but you are over simplifying it, it is very difficult to "switch-off" the ruminative negative thoughts without some form of outside intervention like therapy, medication or some sort of regimented exercise regime. Depression generally cripples your will to do anything, you need someone to help you, help yourself.

Helping oneself would be possible in mild depression, but suicidal depression, it's kind of a tall order mate.

OP needs help from a professional, not naive advice from a well meaning retard.
