It's your choice of course, but is it really worth it to put up with the trauma for a chance at dodging some embarrassment? People who would look down on you for what happened aren't worth being friends with anyway. If a fake-friends kind of social standing is what's more important to you than your own well being, it'd pretty self-destructive imo. You could always get private counselling or something though, not like your friends/peers have to hear of it.
To the main topic now;
That's a lot to have gone through; only true monsters would sexually abuse children. Your anxiety is more than understandable after something like that, but if you remain scared of people and can't learn how to trust them- then it'll remain difficult to nurture your relationships. Trusting, or even interacting with people, is a risk, but it's necessary in order to have good relationships with people. A risk worth taking, I'd say.
If you don't feel like you're ready to trust people yet, just give yourself time. Time can have a healing effect on your traumas. If trusting someone completely is too much for you, you can just partially trust people. This way, you'll get some experience trusting others again while not setting your expectations too high and getting hurt because of it.
One of the ways I urged myself to trust people more was that I told myself that I didn't want to not trust someone who was deserving of it; It'd be sad if someone trustworthy never got that chance to be trusted because of someone else's evil deed. You can also learn to pick up on traits that un-trustworthy people have, and traits of trustworthy people. Observe behavioural patterns in people, not super closely to the point where it's creepy, but just be aware of them.
There are some good people in the world, and a lot of decent people. The truly awful people are few and far between, so be aware that they're there- but just remember that they are the minority; You don't have to be so scared of humanity.
I hope that you can eventually overcome your anxieties, as well as meet some trustworthy people someday.
Sorry if I missed the point and addressed the wrong issues or something like that, or if I just didn't help at all.
