Hi ImSomi,
This is a wonderful story. The tone is dark and full of confusion. It grabs all the reader's attention and makes them want to read on. The reader is wondering if the obviously disturbed speaker will seek help. They will read to the last word to find out. The plot is straight forward and moves along logically. In the story, someone has decided that everything outside of their own thoughts is irrelevant but is becoming unstable in their isolation. The conflict is well defined. There is no doubt about what is going on here. The characterization is fully developed and believable. The story concentrates on the speaker, and they come across a real person. There is no dialogue but it is not needed here. The description is detailed and vivid. It puts the reader all the way into the story. I did come across one structural issue that needs your attention:

1)You have neglected to either double space or indent between paragraphs. You should remember to consistently do this to keep your writing clear for your reader.

The story is consistent in terms of point of view and tense. Great job.
