Serotonin: Disengage/Leave Me Like This

I'm weightless,
Or so it feels.
As I'm laying here,
Leave me like this.

I'm careless,
Or so it seems.
As I'm thinking,
Leave me like this.

I'm happy,
Or so I believe.
Who am I kidding?
Don't leave me like this.
Don't leave me like this.
Don't leave me like this.
Don't leave me, just leave me like this.
