This sounds like more of a medical issue than a legal issue.

None of us has a crystal ball or x-ray vision to know what is in the envelope.

Nothing in your posts indicates any grounds for a lawsuit.

It is perfectly legal....................................................

See a doctor if you need to........................................

The client can object, but unless there is a trial in the immediate future, the judge will usually allow the attorney to withdraw.

The question of how is easy. you were breaking the law.

This is not an issue for lawyers..................

Having cameras in her own house is completely "legal."

None of us knows your case, and none of us can opine. But when I did a lot of mediation, this was a common tactic.
