I Feel Like I Am Never Good Enough

As hard as I try and as much as I accomplish I never feel like i'm good enough. My sister gets all the praise, I have always kind of fallen by the wayside when it comes to stuff like that. I have done a lot in my short time on earth but none of what I do gets recognized. Only my failures and shortcomings. All I crave is a little praise or recognition, I try so hard but it never really comes. I'm so terrified of failing anything now it's almost crippling. It takes so much courage now to put my hand to something because i'm always worried i'll disappoint.
