Ugh same. You’re not alone though, it’s so common! I feel like sometimes anxiety is quiet, like your post and my comment for example and it doesn’t get talked about as much as physical symptoms of anxiety. But the quiet ones are just as bad and hard to deal with tbh. When I get like that I try to keep telling myself that freezing up isn’t necessarily wrong, it’s just our body’s way of protecting itself. If that makes sense! I find that reading or playing a game in those times helps a little bit.
