I am in my late 20s and my painfully shy. Partly by nature as for as long as I remember I have been extremely shy. However, I was also bullied a lot which made my self esteem really low. As a result I am really closed off and never share anything personal for fear of being judged. Fear of being judged as wealthy for example. I have lied A LOT to fit in and now I really regret that.

I have never told people I have a sister for fear of being made fun of.

I have never told people I have an older brother who is a PHD.

I am terrified if i tell people this now they will be upset for never having shared this with them

Can anyone give me advice how to get over extreme social anxiety? Also how do i stop caring what everyone thinks of me?
