"Crazy" is not a clinical term and doesn't really have a meaning in a professional context. It is more of a description that people in general might use when someone does or says things that don't make sense to other people.

How would you explain the behaviors that you discussed? Do you understand what you did or why you did it? I do believe that nobody does things for no reason at all, so I try to figure out what someone gets out of acting a certain way. Can you identify any benefit or payoff to your unusual behaviors?

Once you figure out what the benefits to the behaviors might be, you can contrast that with what other consequences there are, such as that people are concerned, or maybe it bothers them, and then they feel like it is necessary to talk about it and maybe create a plan for what to do when you act that way. And if they do talk about plans, if you are able to discuss it with them and offer explanations that make sense to them and solutions that they can accept, then they will be a lot less likely to think that you are crazy and more likely to listen to you and consider your ideas.
