It is a pattern that you have developed.
You cannot be traumatized if you are in control. And I don't mean in charge, I mean in control of your mind. You have developed a pattern. Our brains develop patterns so that when we do things we don't have to think about them anymore, we do it automatically.
So patterns are good for us, otherwise we'd have to think before we did even the simplest of tasks. But on the other hand, we can develop patterns that hurt us. If someone ever gets traumatized and breaks down in front of others, they develop a pattern, so the next time they get in front of others, or someone says something to us that reminds us of a traumatic event, the mind automatically goes back to the same state of weakness.
So what you have to do first is recognize the pattern that you have. Go in front of others and see how you feel. You should revert back to how you felt when you were traumatized. That is the patterns at work. So now, what you need to do is change the pattern. When you get in front of others this time, say this in your mind, "I am in control, I am in control, I am in control"
And keep saying it in your mind for days and weeks or until the pattern has changed. Then, from that point on, you can never let anyone stop you from being in control of your mind. No matter what anyone does or says do not allow them to make you lose control of your own mind.
You cannot be traumatized if you are in control.
