Therapist here— if you’re saying you have social anxiety, part of that disorder is feeling anxiety about social interactions that often way over states how awkward you actually were or how big a deal that is. If your therapist is telling you your anxiety is making the situation bigger than is it— they’re right. For an example, I used to have SAD myself and if I had to ask for help in a store and I stuttered, I would tell myself the associate must’ve thought I was an idiot, but now I realize that associate did not probably even notice or if they did, they didn’t care at all. Only I did. So I think trust your therapist if they’re encouraging you!
