To give or not to give

As a giver, I gave all my love
until it hurt, and all
my possessions that were
valuable meant nothing
to me anymore.
I was still young on my journey,
and life has shown me
the beauty in giving, but I need
to have limitations.
Takers surround me like sharks,
thirsty for blood from my heart
like water.
Now, in the late years of my
journey, still not free from giving;
now, I give my all to me.
