I am extremely anxious all the time. There are people i have known for years that do not even know i have a sister and two older brothers. I do not want to hang out with them because i am afraid if i tell them this, they will get really upset or surprised at me for not knowing that i have 3 older siblings, if i tell them. Also, never told 2 of my siblings live in the USA. What should i do?

Also, i am usually really shy about talking about myself. For example, i am ashamed to say i went to a private school for fear of people judging me i am rich. Or nervous to say if i am going on vacation for fear of being judged as rich. Also, i am known for being really shy and quiet. I am nervous telling people that i once was a camp counselor for kids because one time i told a girl and she laughed saying she doesnt see me as a camp counselor. That really hurt. Or nervous telling people i was in a fraternity because people wouldnt expect that from me
And if i tell them, i am scared people getting mad at me and say " why didnt i know that before". Also, nervous of telling people what my parents do for a living (business owner)

Do not know what to do anymore. I feel guilty for coming from a wealthier family than most people. I see other people struggling and feel really guilty so i lie about certain things.

What should i do?
