Have you ever wanted to say something like this to someone near and dear to you?
If ever you become aware of me being different, please, ask me what’s wrong.
Usually I will outright tell you, long before it becomes noticeable that something is awry, but if I go quiet, it is because it is hard for me to talk about it. If you’ll ask me, and keep at me until you get to the heart of it, I think it would help.
You might have to pry, but I think it will be worth it. If it is to the point that you notice it, and you ignore it, then we are both ignoring it, and it is not likely to get better.
And please be prepared for the possibility that the problem might be you.
