telling people about your mental or physical health is a personal choice here in the United States of America.

that means only you can decide if you should tell someone and who you would like to tell and why.

for me I do tell some people about my mental and physical health issues such as my wife, my family, my treatment providers, at work its on a need to know basis ie my supervisors know I have dissociative issues and physical health issues so that they can make ADA accommodations when and where needed.

again if you are here in the USA, only you can decide whether you should or want to tell others, why and how to tell them should you decide to do so.

other locations outside the USA may have other rules about disclosing mental and physical health issues, your treatment providers can tell you if your location requires you to tell anyone, or whether it is your choice to do so.
