I tried to be quiet but I failed

I tried to be quiet but I failed
I let my feelings show
I let you down
my honesty prevailed
how was I to know
that I couldn't take it anymore
I misread all the warnings
now I'm where I was before
dreading every morning

I tried to be supportive but I wasn't
everything I tried I couldn't do
I tried to be your friend
like a long lost cousin
but I could not make it through
I had good intentions
I really tried to do my best
but instead I disappointed you
I was like all of the rest
