Have I come this far in vain? (acrostic sonnet)

Some day on heaven's shore, I'll hold the key
That will unlock the meaning of it all.
Until that day, I'll try my best to be
Content to read the writing on the wall.
Keep thinking I should have a clue by now ...

How can so many years have passed me by?
Each time I go back home I feel somehow
Revisiting my youth will tell me why
Each path I walked was diff'rent, yet the same.

Am I condemned this hist'ry to repeat?
God, help me, have I come this far in vain?
Am I forever doomed to face defeat?
I cannot see beyond this awful mess,
No matter how I try, I do confess.
