I try to do my best for
my husband, even though I feel he'd have a better life without me. (I feel I drag him down.)
My elderly mother has needed a lot of care. I also try to do my best for her.
I try to do my best for me, too; yet, lately (and for months now), it's been a pathetic and painful existence of paralyzing depression.
Spring weather will be here soon, which may help.
What/who motivates you to hold on and continue trying?
