Broken down no more hope

hi I’m a 27 year old person that has been caring compassionate and loving.  I have a wonderful family that I would love to repay for everything they have done for me. Lately my depression has been so heavy it hurts.  I met a gir.  l I’m absolutely nuts over and my mood and things chased her away.  I’m so tired of being alive.  My body hurts my mind hurts. 27 years old with no girlfriend behind in my education and with no way out.  Surely there is a better place for someone like me.  I’ve never hurt anyone, I live my life trying to make others happy but yet I can’t find a way to live.
