• Bad memories? Who am I? What?
• Depression? I'm thrilled to be turning two cardboard boxes into a makeshift beverage cooler using floss and shoestrings. I just have to do this one last part. I'll be done soon. Eat without me.

Seroquel. Granted, you can’t drive or do anything cause you’ll be passed out. But you won’t be self-aware!

Alcohol

Ignorance is bliss

Dunno about meds but I know a girl who can make me completely lose my mind :p
