What are some trauma responses that you only realized after growing up?

For me:

​

• Freeze response:
  When someone shouts at me, I become speechless. It feels like I turn into stone, thoughts swirling in my mind, but my mouth is glued shut, and my limbs are stiff and unable to move. Usually, the other person would command me more angrily, "Speak up!" Later, I realized this was the freeze response at play.

• Habitual apologies:
  I constantly apologize for various trivial matters. If I'm particularly anxious, I'll repeat apologies over and over again. Even when told to stop apologizing, I reflexively apologize again. This habitual apology behavior makes me constantly reflect on my faults, even those that aren't mine, and often leads me to doubt myself.

• Fear of seeking help:
  Even in difficult situations, I find it hard to ask others for help and always bear everything alone. I used to think it was because I was too independent and strong.
