Oh, friend. I know how hard it can be. I'm going through the first couple days now, so from here 16 days looks like quite the achievement. It feels like death, I know. There's a reason I'm still awake and perusing the message boards of SR at 4:05am obviously, ha... I know how awful it can feel, and with the added pressure of finishing a daunting task? That must be very stressful.
You're not alone. That's all I know to say. You're not alone.
