Can I sue someone for defamation if that person said to another person privately that I have a mental illness that I don't have?
No, I haven't. But what if the person only told one other person privately and it didn't really harm my reputation?
Even if the alleged defamation was only communicated to one person, you may still have a case. The key is whether the statement was made with the intent to harm your reputation or if the statement has caused actual harm to your reputation or caused others to see you in a negative light.
