Debbie,
I encourage you to apply to YSP. They may so no,or not for now. You've got nothing to loose. I also encourage you to post to us here for any support you need either way. Hoagiesgifted.org is a wonderful resource also.
For what it's worth, Galaxy Girl, my son did get accepted to YSP, and I would place him at a Ruf Level 3. That is very gifted, indeed.
Best Wishes,
Trinity
