Vice

 In all my life I have never had a vice, but only one in a couple of years being addicted to someone I love. And it destroyed much of me too. 

(he was the one I love, he's not a vice, he's only faraway and as I couldn't get to go to see him I took every chance I could to see him from afar and the rest of the people I love and I'll never be able to hang out with)
