How Much Will This Letter of Rec Matter?

<p>I've already applied to the majority of colleges I had interest in, but I may have missed a key letter of rec and I was hoping that someone on here could give me some advice. Here is the potential letter of rec I missed:</p>

<p>My dad has had cancer for 7 years and he was in the hospital getting treatment from my Freshmen-Junior year (died in Junior year). The hospital he went to was a University of Michigan hospital. Since I went there so often (roughly 2 years), I've been able to get to know a lot of the staff there. I know without a doubt that I could get a letter or rec from a handful of people there (doctors or nurses). The kicker is that I am applying to Michigan and having a letter of rec from a doctor at Michigan would go well. Since I already applied, I can't send it in but I was wondering if it would be worth it to take out my application (I made EA) to get this in? Do you think I should get this letter of rec for other colleges outside of U of M? Thanks!</p>

<p>I think it would be a good letter to have, but I don’t think it would be paramount to your acceptance at Michigan. I’m also sorry for your loss. </p>
