There are a lot of people on this website particularly @mom2collegekids, who are extremely helpful to posters in working through these issues and helping to sort out the bottom line. Most are probably sleeping right now, but come back to read their input in a few more hours. This is stressful when everyone in a family is healthy, but crazy stressful when dealing with two members who have serious health problems. My heart goes out to you. It is painful coming to the realization of the true cost of higher education even when your kid is so amazing.
This website, in my opinion, is most helpful in really pointing out and helping people with the paying for it realities. Do come back in a few hours when the rest of America is awake.
