Sharp characterisation, good description. Generally, the first person works, but you have fallen into the trap of starting most paragraphs with ‘I’ which is a little weak…
If the goal is to feel what you were writing I felt it. In fact I even felt a little sick. I can completely identify with the character. I hope you are young and are just writing what is to come.
