the why of life

In contemplation upon the why of my life I find nothing. I must step outside my broken head and try to see the quantifiable. Factually, my life is given to the needs of others. Taking care of everyone but myself. I am a wife, a dutiful daughter, amatuer therpist, online crisis hotline volunteer, pet sitter. This should be a life worth living, but the lies my brain tell me make me think differently. So in the contemplation upon the why of my life, I still find nothing.
