when you try, but sometimes it's never enough.

i know that a couple people have said that i push myself too hard & i know that my parents say they don't expect anything out of me - but sometimes i can't help but feel like an absolute dissapointment? I can't maintain perfect straight A's - I can only maintain them in my academic courses. What does that prove? I'm not well rounded, I can't manage my time properly & excel in everything...what else...I don't even know. I just feel like I've let everyone around me down. I've let them down, one too many times.
