Can I charged with theft and embezzlement from my own business?

My husband and I had a baseball club that we ran as a non-profit corp, Money that came in went back out, The problem was that not everyone paid, in years past my husband and I were able to cover the costs when we had parents fall behind in payments or other parents that just didn''t pay at all. However, over the years that we did this to keep the kids playing ball under our club name it put our family in a financial hardship. So this past season with five teams on the field and more than 45% eith did not pay all of their fees or paid nothing at all we fell short on what the contract stated that we would provide to the players that did pay. Players did not get full uniforms, some teams did not get the proposed number of tournaments, so on and so forth. Now I am being accused of fraud and theft. I have been told that some families have gone to the extent to seek out local authorities to investigate me. What so I need to do to protect myself and my family?
