How can I do more?

How can I express the inexpressible?
The love
the regret
the pain
the years lost
the mistakes made
that led me to where I am today.
Is it wrong to be happy?
To feel loved
to feel good about myself.
Or should I punish myself forever?
No amount of self flagellation
can erase the past
Instead I resolve
to go on
to continue
along life's pathway
and to cope with whatever comes my way
to the best of my ability.
To give out love
to receive love
To be the best I can be
How can I do more?
