How long before opening up?

Yes, I agree, some people seem to feel superior because they haven't had something bad happen to them. That puts you in an awkward situation, as you almost wish they would have something bad happen so they would understand, but then of course that's not right or really what you want, you want good things for others. Hence the frustration and anger.

It's great that you were able to rise above this and understand the issues behind the support group survivor's statements. A tribute to your own progress and character. Well done!
