Trauma from own birth - is it possible?

I was born 6 weeks early and was in the NICU for a week or 2. I struggled to breathe so they gave me oxygen but I was still struggling so they gave me a breathing tube. During this time my parents weren't allowed to hold me but they could touch me. I'm autistic and I imagine the NICU was very bright, loud, chaotic but I don't know. My mom had a bad reaction to some medication she was given right after I was born and had a seizure, so while they were treating her she was gone. From the time I could talk I was obsessed with my birth story and made my mom tell it over and over. I have always been the type who compulsively ruminates over and seeks out things related to trauma rather than avoiding reminders. I obviously don't remember my own birth but I wonder if it can have some impact on development. I feel like I have had symptoms of trauma for as long as I can remember.

The reason I ask about it is that a lot of trauma healing exercises involve breath. I do not like to focus on breathing, think about breathing, deep breathing, any kind of breathing exercises. If I think too hard about breathing I start to feel like I can't catch my breath. When I have an anxiety attack I hyperventilate. It sounds like a "Beagle reverse sneeze". My heart doesn't race or anything unless it's really bad it's breathing related symptoms. Once when I was a kid we were playing greased watermelon in the pool and another kid pushed me under. I couldn't breath for a second. Got really freaked out by that. I want to get past it so I can do the breathing exercises to heal my trauma OR find alternate practices that aren't breathing focused, either way. Any suggestions?
