Uncertainty

After so long, I finally feel like I have a purpose in my life. However, I'm not sure if it makes me happy. I am unhappy. I'm always crying. I'm always hurting. If love is so great, then why does it hurt so much? Something in me is like telling me that this is not right. That it should not go on. I don't know. I don't know what I'm looking for. And for the first time in my life after so long, I'm lost. Again.
