Anxiety and roof of mouth

So I have really bad anxiety and take medication for it but when get really anxious now I press on the roof of my mouth without even noticing sometimes and I been doing it so much that I feel I have myself a bruise is that even possible it’s sore now and even feel it up to my nose and also have troubles swallowing because of it any techniques so I won’t do that? Anybody else press the roof of their mouth with their tongue even without even realizing when anxious?
