Can having (emotionally and physically) abusive parents as a child cause PSTD, and show in adulthood?

Yes. Absolutely. I think in my case, other traumatic events that happened more recently in my life opened the door to that. When I was made aware of what PTSD really means, I then became aware of the reality of my childhood. I think it's a matter of awareness. When you become aware, it can feel like it just happened yesterday and be just as painful as if it did just happen yesterday.

Unfortunately, yes. A couple years ago my therapist decided I have PTSD from childhood. A very physically and emotionally abusive childhood. I've never been one to "be a victim" or share much about my past. I prefer to be a "normal" person! I tried hard for many years to not even think about those things. However, sometimes it's unavoidable. Something will remind me of my childhood, or terrible experiences and it has a negative effect on me big time. Anywhere from just being really sad for a while, to a full blown panic attack depending on what it is, or it can send me into depression for a few days. I don't know a good solution to deal with it or lessen it.

Yes, and it can actually come out years later in someone too if something triggers it.

You probably had a lot of things you experienced that you never processed. Are you seeing a therapist right now? A good trauma therapist can be very helpful, the therapist I had seen explained to me that part of my healing with him was because I needed a witness which is what he did for me.

I am sorry you experienced an unsafe childhood, you deserve to heal from that.

I don't see any therapist right now. It's very complicated where I live. But I think I show symptoms of PTSD like depersonalization and flashbacks, and irritation from similar triggers to those I experienced. I have always felt this way, but I the feeling is more intense these days, although I am far away from my parents (the triggers). I am also unemployed, and stay at home most of the time because of social anxiety, and I think this gives me a lot of time to think about what happened to me before, with little distractions.

Is it possible for one child to experience PTSD, while another doesn't from the same abusive parents? I feel I am the most affected, as my siblings seem to lead a normal life to a large extent, while I am not. I wonder if genetics may play a role here.

Background Noise, genetics definitely play a role; you may have inherited a predisposition to PTSD. It certainly is possible for one sibling to have PTSD and another not to, both having gone through the same amount of trauma.

I'm sorry about your abusive childhood, background noise.

mine was bad too

my parents should be absolutely ashamed of what they did (not only to me, but what they are currently doing to my younger siblings)

but they chose to run away from it and start a new life in africa

not my problem
