TL;DR: I haven't told my parents I'm having a scheduled c-section and I'm terrified of dealing with their reaction/judgment/invasive behavior, and morally conflicted about lying about my delivery.

I'm about to have a baby in 2 days (!!!) by scheduled c-section for medical reasons.  I've know about this for about a week and a half now, and I'm very happy, excited and at peace with the whole thing.  However, my parents (Nmom, Edad plus I'm adopted, have PTSD from abusive childhood) are causing me nearly unbearable anxiety over it.  I haven't told them because 1. it's not any of their business and 2. my Nmom loves to play "doctor google" and knows better than anyone else about everything.  If I told her this news, it would be instant panic, criticism, and spamming with text/emailing articles about my condition (breech baby, really not that big of a deal), what I should be doing, how it's my fault, how my CS will go horribly wrong, etc--basically the exact opposite of a calm, supportive reaction that any soon-to-be mom needs.  This is a lady who subsists/gets off on fear and anxiety and I'm naturally the opposite way but need to shield myself from her horrible energy because it's so triggering for me.  I'm not NC with my parents because we live in different states and I have a great relationship with my aunts and uncles so I can just keep my parents at arm's length but they sure do try to get in...  and once they do it's a nightmare so they are on a permanent information diet.  

I also just have this horrific dread (regardless of what kind of birth I were to have) of suddenly picking up my phone a few days after delivery to find a million text messages from people, but specifically from my parents... frantic texts, missed calls, demanding facetimes, intrusive nonsense etc and then all that turning to anger/abuse/gaslighting when I don't answer or whatever.  I'm 33 years old and have been completely independent from them for over a decade but they still try to control me and act entitled to opinions over every choice I make and information about everything I do.  Since they've never had a baby of their own, I fully expect them to have zero understanding or tact in dealing with a newly post-partum mother (me) and her family and respecting their need for peace, quiet and privacy.

So basically, I could just make something up like "oh gosh I went into labor it all happened so fast, here she is!" and completely shut down any questions, or tell the truth and deal with the bullshit.  Normally, I wouldn't hesitate to tell a lie of this sort (truly, it's no one else's business what's in my medical chart) to protect myself.  However, I'm very conflicted for 3 main reasons: 1. I think lying about this contributes to the stigma around c-sections which I'm very much against, 2. as an adopted person who knows nothing about her own birth AND a first time mom making the safest choice for her baby, I don't WISH to hide this information and believe it's disrespectful not only to myself but to my daughter to "cover it up" and 3. since I had a really bad childhood, I lied a lot to protect myself and survive and was therefore labeled a liar by my abusive mother.  Only as an adult no longer living in a terrifying, abusive environment did I discover that in reality, I am not a liar at all, in fact, I'm honest to a fault.  So my fear is that if I lie about how my daughter is born and they eventually discover the truth, they will use that against me and it will become a huge issue (again... only crazy people would make someone else's VERY personal medical history into a big conflict but that's who I'm dealing with).  SO basically I'm caught between kowtowing to them and protecting myself in the short term and also having to keep track of a lie I told (the worst) versus sticking to my principles, standing up against CS stigma and being proud of my daughter and her birth from day one and dealing with the inevitable shit storm.  

What to do?  Seeing my therapist about this today, just wanted to cast a wide net for advice.  Thanks for reading I know it was a long one :)
