Attaching a note to my transcript?

<p>I spoke to my guidance counselor today and I was going to ask her to write a letter to go along w/ my transcript to the schools and she told me I have to wrtie it.
My GPA is low and I missed a few months of school for eating disorder treatment, and even when I returned to school My life was so hectic with doctor and therapy appointments that school became second in my life. My main focus was recovery. i am now full recovered. I was going to write about that.
and I just need advice about it.
How long should it be?
What should I say?
or anything else that would help me
My personal statement is about me overcoming bulimia, so i dont want to repeat the same things.
THANKS.</p>

<p>I am a parent with no particular expertise about this issue but here’s what I would do: Write a cover letter that you will send to each college you’re applying to. Explain the reason for your low grades–your illness and time away from your studies to get well. Then make sure to say that you are fully recovered and that you are ready to take on the challenges of a rigorous college career. Good luck and continued good health.</p>
