Hey, everyone!
So I'm looking to go to a Big 10 school this fall (though not one where recs are required - will get them though

). I'm looking into the sorority recruitment process, and I've had a few questions come up:
1) I had to take a year of medical leave earlier in high school, so I'll be a year older, and I'll have 1997 in my recruitment forms, I guess. Do you think it'd hurt me in any way, since I'm supposed to be a sophomore, and should I bring it up? I'm already planning to talk about this with my recommenders, but what about mentioning this during open houses/invites?
2) I'm also thinking I might have to bring up being out of school anyway, due to the impact it had on my cumulative GPA, which meets all the requirements, but is not something I'm proud of. And if so, would it be better framed more ambiguously as "medical leave," or should I be more honest to sisters and delve into mental illness related areas, or is that a tricky area? *EDITED for clarity: what I went through is definitely not something I'd bring up myself, but I've found that with half the people this comes up with, they tend to ask for specifics, just out of curiosity really. I don't mind usually, but in the context of rush, I really don't know what I should say if I get a follow up question about the "medical leave."
3) I've been hearing about letters of support, but I'm still a bit confused on whether they'd be good or just annoying at a school that already isn't that big on recs. I'm also wondering when they'd have to go out and how they're different from letters of recommendation.
Thank you for all your insight!
