Who am I..?

I'm always trying to figure out
Why I am the way I am
I'm shy I'm quiet
I'm loud and excited
I dance and express myself
Yet I stay in my house
Scared to move
Some call me lazy
But I'm not sure why I am the way I am
I can be extremely sensitive
Yet fiery like a lion
I am a Pisces not sure if that effects me
I follow the traits of a Pisces
My head is red and wild like a lion
Maybe that is why I'm feisty
My eyes are blue
Like an ice cold ocean
Is that why I am deep and sensitive to emotion
I'm not sure maybe I have learnt the way I act through my up bringing
Or is it the genes I have been given
