This action appears to be a serious violation of your privacy. At a minimum, you should put your concerns in writing and send them to your manager and the human resources department.
There is a thing called "public disclosure of private facts" in the invasion of privacy world. The employer has no right to pass on this information about you. I would write to your employer and send a copy to human resources and/or the president of the company and tell them your did not authorize the disclosure of your private information and insist that this stop immediately. I would also express to them that this has hurt you emotionally and this has been humiliating. You may want to consult with an attorney on this or if this behavior continues.
It would not be inappropriate for the information to be disseminated to those within the workplace who would be responsible for assuring your compliance with the follow up program. However, dissemination to others without a need to know is a violation of your privacy rights.
The tough thing now is to decide what you intend to do about it. While you might have a claim for invasion of privacy, you have not faced any financial losses caused by it, so your damages are somewhat undefinable. On the other hand, you have an employer that has demonstrated a willingness to work with you when it may well have been within its rights to simply terminate you.
Think long and hard before deciding to declare war on the employer. Good luck to you.
This answer should not be construed to create any attorney-client relationship. Such a relationship can be formed only through the mutual execution of an attorney-client agreement. The answer given is based on the extremely limited facts provided and the proper course of action might change significantly with the introduction of other facts.

It's tempting for attorneys who read this post to hear bells in their heads about privacy causes of action. But there are a significant number of potentially critical and determinative facts that you have not shared or considered here.
Your program, presumably pertinent to substance abuse of some sort, necessarily followed some sort of behavior that was visible to your employer. Was that behavior also visible and recognizable to co-workers? Did it occur at the workplace? Was it the sort of conduct that most employees would expect to have led to termination? You say "every one knows my situation." Is that solely because of the 3 emails by management, or did that occur in the first place by the conduct that got you into the testing?
If you were in an impaired state at your workplace, visible and recognizably impaired, or otherwise known to your co-workers to be UI, and your employer put you into a testing program rather than terminate you, and everyone knows about your situation because of your conduct and the fact that you were not fired for it, then you most likely do not have a sound and worthy privacy claim.
The other issue that needs explicit investigation is what -- if anything -- you signed when you agreed to the testing program -- if you did agree, presumably in exchange for not being fired. It is a growing trend among employers, particularly those in industries where any substance abuse raises potential industry-related dangerous workplace conditions, to require the affected (unterminated) employee to agree to disclosure in the workplace of the fact of the monitoring program. These employers view this disclosed information as a significant instructional objective for other employees. You can argue with that view, of course, but if you specifically agreed to it in order to avoid termination, you don't have sound actionable privacy claims now.
No legal advice here. READ THIS BEFORE you contact me! My responses to questions on Avvo are never intended as legal advice and must not be relied upon as if they were legal advice. I give legal advice ONLY in the course of a formal attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by joint execution of a written agreement for legal services. My law firm does not provide free consultations. Please do not call or write to me with a “few questions” that require me to analyze the specific facts of your history and your license application and prescribe for you how to get a State license. Send me an email to schedule a paid Consultation for that kind of information, direction, and assistance. My law firm presently accepts cases involving State and federal licenses and permits; discipline against State and federal licenses; and disciplinary and academic challenges to universities, colleges, boarding schools, and private schools. We take cases of wrongful termination or employment discrimination only if the claims involve peace officers, universities or colleges.
