I know you've tried

Gem of my very heart:
i know you care
and i know you have tried hard
to help me find my way
to see me safely home
home to where i belong...

I know you are hurt
caught in between - sandwiched;
i know i'm the cause of the hurt
and i'm sorry that i cause others to be so hurt
by the things that i'd blurt -
and the things that i don't blurt...

I'm sorry, i'm sorry,i'm truly sorry -
that it has to come to this:
that i cause others to be really hurt...
i'm sorry, i'm sorry, i'm truly sorry,
that i cause misery to one so young - i hurt...

Dear God,
Have i been utterly selfish to want to carry on?
have i ever gone wrong, without realising that i'm wrong...?
do i need to find happiness, at others' expense?
or do i call it quits - relieve them of their misery...?
