I am also a VERY sensitive person and struggle horribly with similar as you--major depressive disorder, anxiety, depersonalization and then also along with PTSD and on and on.....

I believe it's best to have the mindset like Maya Angelou said-- "when we know better, we do better".
One can't blame themself- when one is a child and/or teen, for NOT knowing what was going on and feel you are in some way "bad" for it.
You know better now and I bet you will act in positive ways on this subject from here on..... a child shouldn't be blamed for being born into something unjust and wrong. It's not your fault.

Maybe volunteering within the realm of this whole prejudice thing, would help you to feel you are making a change for the good, helping with something that needed changing....

Shame can be a very powerful force that stops us from being our full self...... searching for ways to shrink that guilt may be of some help.

best to you
