Extreme anxiety of being judged - need help

i am in my late 20s and I am extremely shy and have a lot of social anxiety. I am scared to tell my coworkers that my brother lives in the US for fear they will google him. He did a phd in his field and he would be easily searchable as he has a top job. Scared they will judge me and say he is rich for example because of where he works. I am als scared of them finding it weird of why i have not shared this with them before.

Does anyone have any help? How can i stop worrying so much what people think of me? I am seeing a therapist and i am planning to go to the doctor to get medication. Its really draining living like this.

Any advice?
