Mums who had complicated\traumatic births - when did it really hit you what happened?

I had a failed forceps delivery followed by emergency c-section under general anesthetic. But baby was full term and didn't need the NICU for which I'm incredibly grateful and came home on day 2. Day 4 now and I had a kind of unexpected breakdown about what my partner, I, and baby went through (despite having received outstanding care from the hospital). My MIL who had a traumatic breech delivery 36 years ago had predicted exactly that timeline for me suddenly processing everything (and she was there with hugs and reassurance immediately). So, others mamas in this sorry club, when did you start to process it and how long might I be randomly bursting into tears about it? My love and hugs to all of you🫂♥️
