Very good job!
On an abstract level, I do worry how well so many of the basic mechanics we have work for grim stories (remove, destroy, block, feeling trapped, etc.). It would be great to push to turn these to tell uplifting stories.
The power of a story written in first person is also a thing to be reckoned with! You've used that very effectively here, and the writing is good; however, that also creates a problematic point too. It would be a good idea to change the title on the game - if people expect a game where a person deals carefully with their depression (as the title might suggest) and they get a suicidal person instead... That's not great. Emphasising that this is fiction and adding a trigger warning for self-harm would be a good idea.
... That wouldn't be as much of an issue if you hadn't overall done a really good job. With power comes responsibility ;) Well done, and I look forward to seeing how you grow with additional mechanics and nuance.
