Tote,
I really fight the thoughts of 'lifes not worth living', and I do this as soon as I become aware that I am thinking it. Once this thought pattern has a hold in my head, it is locked in for a very long time, and then the 'fight' is unbelievably hard. Not to mention, very dangerous.
So, try and fight that thought patter as soon as you become aware of it, I tell myself, that thought is not an option, and I really dig my heals in.
Good luck
Karen, (((((HUG)))))) Let it be, be still, stay strong, this too shall pass, I promise you, xx
