Silence does not mean you are being moody. Sadness does not mean you are being moody. Crying does not mean you are being moody. Anger does not mean you are being moody.
I dislike the word moody. There is a difference between using the word moody to describe someone and using the word mood to describe a current emotion or state of mind. Maybe it is because I have always felt the word moody has a negative connotation. I’ve used it to describe someone, I bet most of us have too. But with age and life experience comes wisdom. When people are struggling they are not being moody, they may be having a hard time dealing with their own challenges and their emotions. Stop labeling and start understanding. You never know when you will be asking for the same.
