Extreme social anxiety - need help - lying about myself

I am in my late 20s and always had a lot of social anxiety. As a result I lied a lot to fit in. I lied that I went to a public school instead of a private school, I never said my brother did a phd, or that my parents are business owners. All of this because I am afraid of being judged as wealthy.

I always feel really uncomfortable sharing any details about myself for people possibly judging me as wealthy.

Anyone have any advice?
