Por lo luchado, lo dolido

[Michael30000]

Hello everyone,

Below is a dedication from the book Cuenta contigo by Patricia Ramírez Loeffler.

"A ti, amor. Por lo luchado, lo dolido, por la esperanza, porque nos lo merecemos, por nosotros. Te amo."

Here's my attempt to translate it:

To you, love. For what we have fought, for what we have suffered, for hope, because we deserve it, for us. I love you.

Is my translation correct?

I must admit I'm not sure what "Por lo luchado" means and what "lo" means in "porque nos lo merecemos."

Thank you.
