Hello lavendae,
I've had PTSD most of my life too and didn't know they had a name for it until about a year ago. It sounds like you handle yours a bit like I do. I keep a wall of protection around me and don't like to discuss it much. It usually causes more stress for me when I talk about it. It is so much easier to type it out then actually talk about it face to face.
When I first came to the message board I had held so much in that I think I actually forgot how to talk about anything. It took me awhile and still have a hard time sharing about myself.
Please read through some of the posts and make yourself at home here. Start a new thread anytime you want to. You read my story above and know I've been through it.
Domestic abuse can cause a lot of damage. Especially at a young age. I went through the worst of mine from age 17 to 22. There wasn't much help for it back then and PTSD was unknown too. You have a lot available to you now. No need to rush things. Take it at your own pace.
It's safe to talk about it here when your ready.
Hugs,
MG
