I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear that this happened.
Defamation requires an UNTRUE statement of FACT. If the statement you posted related only things you personally observed, that's not actionable. Statements of opinion also are not actionable. Accusing someone of committing elder abuse IS actionable if it's not true, so you have to look very carefully at the statements you made to verify whether they are true, or whether it's an opinion.
Also, the plaintiff has to be able to prove that a reasonable person could read the posts and be able to tell who you were talking about. It's not enough that this person figured it out - would other people know? Because they have to be able to prove reputational harm.
The law allows people to sue when they believe they have a case, but truth is an absolute defense to a defamation action.
