Can a reserved reclassification school slot be canceled?

I'm awaiting orders for an ADOS tour in Missouri that start soon. My unit is attempting to force me to attend Phase II of reclass school even though I'm having severe family problems. The school is only 2 weeks long, however, my wife and I can't wait because if we don't go we will be both homeless and jobless. The unit allowed another soldier to cancel their reserved seat due to family problems, but are telling me now that I'm having problems that cancelling the school slot is unacceptable. I was told verbatim "You're on a mission, your problems will be treated as "personal". So in other words, not their problem. Additionally, I didn't have access to a computer to complete the application so my unit forged my signature in order to submit the application. What should I do?
