Is there....?

My outside tells a story
it says I'm happy in many ways
but inside I'm slowly crumbling
because the sadness always stays.

I tried to make the right choices
people say I'm a positive person
but I've made so many damn mistakes
from each mistake-I've learned a lesson.

I have to put up this strong front
because people seek out my advice
they don't realize it is I who's stuck
I have failed more than once or twice.

This smile on my face is fake you see,
get to know me on the inside
then you'll see me as I am
you'll know each time I've smiled, I have lied.

But why is it I feel this way?
I have a house, two kids, a man
If I can't make myself happy
then is there anyone who really can?
