You don't need to be too worried. Although, I would recommend not to do the same thing again.
In common law, there is tort called public disclosure, a type of invasion of privacy, which is the unreasonable public disclosure of a private matter, even though true, which would be highly offensive to a reasonable person. Therefore, even if you published a true matter, as long as the matter is a private one, not newsworthy, and a reasonable person would find it offensive, you will be liable for the damage.
