Become needed. I think to some degree it's a reverse "imposter syndrome." The dark parts of your mind trying to convince you that you're not needed. You're more needed than you know.
Is it your dark thoughts trying to convince you or just giving you a reminder?
Absolutely trying to convince me. I know for a fact that I am no burden. I know I am not useless and that wherever I go I may be useful to others. I am not despondant and although those thoughts appear from time to time, I know they are untrue. This goes for everyone, whether they see it or not.
