The main character lacks background story, and his motivation to "take revenge" and "live" is meaningless. Words "wrath" and "vengeance" make no sense. WHAT is he taking revenge FOR? Who has ever done any harm to him to make him so bitter with life, angry and want to gain freedom?
You've missed a very important part where the boy makes a pact with the demon. You need to write it in end, but in much more detail, as a flashback, starting with words "I remember now.." or similar to those, once the main hero is sent into darkness.
The description of darkness, when the character is engulfed by demon, is too short and does not add to the atmosphere of the piece and does not describe well enough the feelings of the hero when he's captured. You need to use imagination on this one, and not just throw words like I do shadows and highlights on a 2D picture.
Need to describe the meaning of "living hell" in Part 2 of this somehow. i.e. what happened after that. Or at least describe it in this part but briefly.
I've spotted 5-6 terrible mistakes, fix them, and you misspell "supposed" with "suppose" everywhere.
Overall, the piece is very great, ESPECIALLY in the bathroom part/searching for pills/returning from work part, before and after that it feels rushed and really lacking. But the tension and atmosphere in the part that I mentioned is SPLENDID! I LUV U True horror right here. But you need to work more on how you describe stuff that happens.

Yep, but it can be creepier if I want it to be. But, this is fine right here!
