I'm Messed Up

I am not really sure what my problem is. But it seems that no matter what happens in my life, I am never happy, it's like nothing is ever good enough. My friends aren't good enough, my job isn't good enough, my marriage isn't good enough and so on. I put such high expectations on everything that almost always I am let down and that frustrates me. I feel like I have settled so much in my life. What happened to the little girl who wanted to be a top rated district attorney? What happened to the girl who knew she would do great things and change the world? I have come to realize that life as an adult basically sucks ass.
