Being around kids can trigger my trauma

It just reminds me of what I went through or I get upset because I didn’t get to have an normal upbringing. I don’t hate kids , far from it , I just can’t be around them on some days because my brain gets really triggered. It was like that yesterday when I first met my best friends toddler. I couldn’t ever raise kids of my own. No way. They would constantly trigger me if I attempted that. I don’t wish any harm to them or anything like that , it’s just that my brain likes to play out every single traumatic thing I went through in my childhood when I’m sometimes around kids. Sometimes my siblings trigger it. I think I upset my friend when I told her. I just wanted her to know why I don’t feel like going to her house For an while.
