Interesting concept, very flawed realization.
I will not criticize the artwork and the sounds. I actually liked the audio, it was raw but experimental. It got the job done.
What I will criticize are two things that ultimately break your game.
1. Pacing: if you want to tell a story that is this short and simple you have to keep things tight. Having the player stare at the screen for minutes while doing nothing is not a good idea. It is so rare when you are required to do anything this might as well be an animation.
2. The story itself / mundane problems: I know that depressed people tend to view small problems as huge crises but your story really offers nothing to justify a suicide. All we see is a person who cannot face even the smallest of life's problems. Getting berated for playing video games..having a bad day.....simply put: there is nothing here that warrants a motive to kill yourself. Worst case scenario: people will just say "first world problems".
If you had presented real tragic events (loss of a loved one, fatal illness, loss of a limb, murder etc.) then I could see how this ends in a death but not this way. I get the feeling that you wanted to make a game about suicide but you did not spend time to develop a story that leads up to that point.
