Habits of masking to avoid feeling dump

Do you sometimes have the feeling that you do things, even you didn't understood it right, out of the habit to do something then to ask and feel dump by the reactions?

And can it be that extreme that your brain makes the decision to do it (perhaps because of ADHD) without truely thinking about doing it? Sometimes even if it feel dump afterwards to do it exactly like that.

I hope it's not too complicated.
