fighting a losing battle

No matter how much I try.  No matter how much I learn.  I still feel that I am a casualty in a losing battle.  I open myself to the entire universe.  Share everything that is me.  Yet I still watch as the blood drips from my lips. I don't know if that's simply my insecurities,  Or if in fact words unsaid hide that which would hurt me.  I wish I knew.  Truly I do.
