Hello understandmoon: I'm sorry you are only now receiving a reply to your first post here on PC.

Welcome to PsychCentral… from the Skeezyks!

I hope you find the time you spend here to be of benefit.
Different people can be traumatized by different things. What you describe would certainly have been traumatizing for me!

I guess time will tell to what extent this experience will have a lasting effect on you, if it does. From what you wrote, it doesn't sound as though fighting is something you've typically been frightened by in the past. So it may be that the effects of this particular experience will fade over time. That's about all I can say with regard to this.
PsychCentral is a great place to gain information as well as support for mental health issues. There are many knowledgeable & caring members here. The more you post, & reply to other members’ posts, the more a part of the community you will become. Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
