Addiction
Addiction is a crazy thing. Making you do things you normally wouldn't. No matter what your drug of choice is, it alters you, lowers inhibitions, hell, it even makes you crazy. You don't realize in the moment what you're doing, you don't realize who you're hurting. You do things and convince yourself you're doing it to protect the ones you love. Hiding from those you love instead of telling them there's a problem....
