It doesn't matter if your equipment is paid for or not. We must still pay ourselves back the cash we took out of our account to buy the equipment, plus the interest on that capital will it was tied up in holding equipment rather than earning interest or income. There is no such thing as free money. It always has cost or value that should be accounted for, not ignored so you may justify operating for cheaper rates. That's a fantasy, to ignore this.
This is the first time in a very long time I've seen anyone get upset because someone else is happy. I cannot even imagine going through life and being that miserable all the time. I truly hope things get better for you.
