You provided one example but I would need others to determine if it’s a problem. Even if you are guilty of over-disclosure, it does not warrant your harsh self-judgment; it is a very correctable problem.
Generally speaking, you want to be cautious about what you disclose to others because that information can (and will likely) be used against you. It can make you vulnerable to people looking to exploit your vulnerabilities. Too much self-disclosure can also make people feel uncomfortable.
Alternatively, sharing personal information can be a good way to connect with others. It can make you seem friendly, trustworthy and open-minded. However, disclosing too much will have exactly the opposite effect. It will drive people away.
Hypnosis would not help with this problem. Counseling is the solution. It could help you learn how to properly interact with people, should it be determined that correction is necessary. In counseling, you can examine the pros and cons of sharing personal information, how and when to do it judiciously and how to protect yourself against social predators. A good therapist can teach you these social skills. Good luck and please take care.
