Family stress and work related bullying

I worked for my family. I was hired on to do menial labor and ended up doing a very good job at a wide variety of different tasks not listed in my job description. I purchased all raw materials, I did all sales, I finished quotes for engineering staff, I arranged competitive shipping rates, I brought in one million dollars worth of new business. I was paid hourly $12 50 an hour. I was harassed into leaving the company due to the inaccurate belief that I called OSHA and they were fined over $13,000. I was constantly yelled at. My training consisted of being told to Figure it out about 14 times a day. I finally figured out that the partners did not know how to run the ERP system themselves. I was replaced by three employees all males all salaried. I worked lunches breaks days off,
