I could not help but be moved by your plight. I am a newbie on this site, but if I were in your position, I would begin with calls to my elected officials. Tell them your mom is a senior citizen. This sort of problem is what politicians are made for. Begin with your Senate rep, the Democrat Bill Nelson

And Marco Rubio:

If you have the equivalent of New York City's City Council, call your rep there, and your state senator, Vern Buchanan:

As an elected official of mine once said to me: "We love to get calls that give us something specific to do. It wins votes." Good luck.
