Who Am I?

Come' on and figure out who I am!

Not everyone has me,

No one needs me,

I'm kept up away,'

In the room of despair,

I'm chilled,

Served with grapes,

Makes the world...

Go away,

I'm sold everywhere,

I'm available to everyone,

From the corner to the store,

But I'm troublesome

I make you confident,

I encourage Y'all,

I chill ya down,

Till ya fall,

Adults gulp me down,

Kids admire with disgust,

Teens are curious,

Addicts are in love,

Who am I?
