When will I ever be enough?

I don't even know where to start.  One thing after another has been going wonky in my world, and today might just have been the last straw.  I love how I have so many people telling me not to be so down on myself and that I'm fabulous, yet then they turn around and tell me what a crappy person I am.  It can't be both ways.  I'm not saying that I'm perfect, cause I certainly am not.  And I am painfully aware of my flaws (real and imagined) all the time.  But if I'm so horrible, why do people even want me in their lives?  I just don't get it.  I will admit that I am the ultimate people pleaser and I have trouble being completely upfront about stuff.  It's cause I want everyone to like me and no one to be mad at me.  So I don't like to tell people stuff I think they don't want to hear.  Or stuff I don't want to admit yet.  I'm working on it.  I just don't understand how it is that I continue to have these people in my orbit who I can just never make happy enough.  I am always doing something wrong or not enough or too much and it's seriously making me insane.  And I get that if it's happening with more than one person the common denominator is me, but I just don't know how to fix it.  Is there a book I can read?  Or a workshop?  Or can all you perfect people please tell me what it is that I can do to finally fix the piece of junk that is me?

I realize that this is all overly dramatic and some of it is probably because I'm just so freaking sick about all this right now.  I'm tired of feeling like I'm never enough.  I want to believe I'm enough, but I just can't ever get there.  And today is just another example of how I'm falling short of the mark, again. Ugh.  That's all I've got.  Ugh.
