A lot of trauma is internalization. You blame yourself. It's made to be your fault. You're told you're a terrible person. Get mad about what happened to you. Anger is your tool for being pissed off and asserting your boundaries.

Anger is very hard to control, can easily backfire into self-loathing and cause you to strain existing relationships, which can also further fuel internal anger at oneself. If you get mad about what happened to you and start lashing out at others, you risk isolating yourself and deepening your depression.
Fear and anger are like look and leap. People who can't feel anger can only look and never leap.
Why is this the case?
