Private School Woes

Before I even thought about having kids, I knew I was going to send them to a private Jewish day school. Knowing the area in which I live, it was really the only plausible option. There are very few (if any) religious Jewish kids in the public school system because there are a ton of Jewish day schools around, and that's where all of the kids go. I knew it would be expensive, but I felt so strongly about it that I knew I would just have to grin and bear it as best I could. So I did. We got scholarships (as nearly all families do), and it was manageable...somewhat. But as the years went on, the bills grew even as my salary did. Going to school meant I wasn't working for several years, and now we have to make that money up somehow - plus pay back the student loans. We were getting help from family, but circumstances (death, retirement, etc) has now rendered that impossible. And so now I face taking my kids away from their friends and away from an excellent school solely because I can't keep pulling money out of my home equity line of credit to pay for their school. While I am sure Boston Public Schools are a fine place to get an education, I don't know how I'm going to be able to give them a good Jewish education on top of it. Meanwhile, they're going to lose probably all of their Jewish friends because they so rarely go on play dates and don't go to synagogue that often either. I'm seriously distraught over this and don't know what to do. I have cried so many days over this, and I can't bring myself to make a decision one way or the other. Kill myself financially and allow my kids to have the education I want them to have (that they deserve) and to keep the friends they have tried so hard to make or put them in public school so I can pay back my loans and eventually we'll have money to live on and not keep taking money out of my house to pay the bills. I've prayed on it, but the L-rd isn't giving me any ideas. What do I do now?
