If that was a serious comment and you are genuinely concerned about people being able to make comments without degrees and certificates, then I think you really may need to be seeking the expertise of an expert. The way most people are able to interact online is much more open and free. I understand that if you have had extreme trauma or have large underlying problems, then this sort of interaction may be unhealthy for you. Unfortunately, it is up to you to take the steps to put yourself into a safer environment. If not, then things may get worse for you before they get better. I hope you are able to find the help you need if that is really the case.
