There is a Life's Tenant

There is a life's tenant,
which I find is true.
I need to care for myself,
before I care for you.

When I'v ignored my need,
and helped another,
it's as if I was crazy,
to help my brother.

There is a fine line,
when pondering about the who,
for I am more important,
to me but not to you.

Is it hard and cruel?
I suppose it's true.
Not taking care of me,
then I am nothing too.
