Repeat to yourself that Robin really isn't gone. Time has proven that fooling yourself to believe the things you had no control over.
Keep going through the photos you had together. Look at every single detail. Was this a sign he was going to die? No, no, it was just you not protecting him enough. Stay up every single night staring at the ceiling, either attempting to gather the courage to turn your loneliness into nothing more than a bad dream or praying just for one second that he was still alive.
Go out and buy chocolate from the girlscouts, watch as they smile once they had your money, never stop pretending like you're okay.
Talk down on yourself whenever possible. Robin died because you didn't deserve him, right? You must've done something really bad, and it's nearly impossible for you to cry now.
Avoid your friends for weeks, even though they're the only thing keeping you alive. If they really cared, they'd come. But they won't. Who cares?
*Allow yourself to lose interest in the things you love. Watch as you take the backseat to the world around you. Become a secondary character in your motion picture, don't fight it. *
But most importantly, drown every single one of your feelings in old stolen rum. Learn to love the taste of it dripping down your throat and find comfort in the warmth coming from your stomach. You're drinking bottled love now.
You didn't need other people to drive away your loneliness. You just needed to find a way to talk to it.
