Lithium

You helped me through my worst
My friend whenever I needed one
You became the shadow I could lean on
I'm addicted to you, lithium

Maybe love's the spell you've put me under
When I'm with you I'm not the same
Withdrawal symptoms when I don't have you
Keep coming back for more
Again and again

Maybe I'd lose a part of myself
Maybe I'd just go on anyway
You were my lithium and not the drug
Who I do love
But in a yet undefined way.
