Who am I?

I'm a teenage girl
I get sad for no reason in a moment and in the next I'm laughing at the most stupid things
I take simple things too serious and complicated things like they were nothing
Sometimes I like to cry alone in one corner, others I want to cry in front of people so they can comfort me
I like to laugh with everyone around me but at times I hide my smile because it is inappropriate
I argue with my parents, with my siblings, with my best friend
I even argue with my self sometimes
My life is a mess
It sucks
But still I find reasons to raise my head and keep trying every day
And one day I'll look back at this and I won't regret any of it
Because these experiences are what make me the way I am
And I never regret being me
