My hidden passion for singing ~

Since when I was young, I love singing. I remembered when I was younger about 4 I used to sing in my dad's car and this brings the family closer. But look now in this condition... we're not close now.
Still.. I continue to sing my feelings and wrote a few songs and kept them but I eventually lost them. I remember I sing them to my friends in the past and they enjoyed it though it was embarassing..
Now, I keep this singing voice of my in the back of my mind.. Mostly, I would just open my singing to my close friends or to express my feelings.
Up to now those I mostly sing to is myself or my sister.
