unfortunately this is true. but then it isn't a true test of friendship if you wave goodbye so easily. yet if you are unable to challenge yourself by lifting a finger, then do your friend a favor and be honest about it.
I am thankful for my struggle because without it I wouldn't have stumbled across my strength. I am thankful, struggling, and it's so hard, but thankful, and will continue to struggle till I get to where I'm going.
