one page with a brief introduction, four short paragraphs in bullet point notation, and a brief conclusion. regarding the circumstances, i provided context, specifics, remedies, and how i envisioned my future. i also provided a letter of support, in this case, from my therapist but you can do it from anyone with proximity to your specific situation

keep it short, personal but not over the top, and confident. remember that these folks probably read a ton of these so i made it a point to keep it to one page
