Ahhh shit. Use is getting heavier and heavier

So, I woke up this morning before class, extremely stressed so I popped two bars and went throughout my day (with little memory). As Im coming down, I go lift weights like a mother fucker. Get home, drink a little, pop another bar, do the last of my heroin and I have to teach a kids sports class in less than 2 hours. Fuck, how did I get here
