Barbara - we are not the people to be asking.
You need a financial advisor. Do you have a family member, or friend, who can help you navigate this situation? Don't go it alone, there's too much at risk. It's possible that you've broken the terms of your reverse mortgage.
It's also possible that there are merely scare tactics and they want to renegotiate your reverse mortgage, and feel that if they scare you upfront, you'll be more accepting of whatever paperwork they put in front of you.
You may also want to contact a real estate attorney to assist you. Asking a bunch of people you don't know, online, is a mistake.
