Still wanting closure

I am wondering why I can't get closure on what happened to me. I bought a franchise that was a glaring bad investment. It had no chance of working. The whole system is very sleazy. Both the franchise and the company that lead me to it. They are using people and taking advantage of those just wanting to make a better life. Can you thing of a more low-life scummy way to do business. Barely legal but most certainly unethical. I wish I could get over the loss. I have a hard time putting this behind me.
