Is PTSD from severe bleeding a thing?

Hi! Just had an emergent hysteroscopic myomectomy on Tuesday to remove one submucosal fibroid that put me in the hospital over the weekend. We discovered in December (due to an ultrasound to check my Mirena which had slipped out of place) that I had three fibroids, two of those submucosal but all relatively small (2-3cm) so the dr wasn't super concerned. During the December Mirena debacle (the fill in Dr I saw removed it which threw me into hormone withdrawal) I had severe bleeding and large clots, but thankfully hemoglobin only dropped to 10 before we were able to stop the bleeding. [My hemoglobin was at 15 as well as a high RBC count in October so my Dr encouraged me to follow up on that in case I have a blood disorder. I haven't had a chance to do that yet due to all of the bleeding, but it is on my radar.]

My Dr put me on lo loestrin since my Mirena was gone, and things were ok for a couple of months, but on day 9 of my third pack, I started having heavy bleeding episodes that would come and go after a few hours. I saw my dr last Wednesday, and she told me to double up on current low dose BC and then to move to a stronger BC Rx once that pack was done. She thought I needed more hormones (I'm also 49 and perimenopausal, so all sorts of wacky hormone issues!) The next day, I started bleeding more heavily and consistently, so I called in for a TXA Rx to get the bleeding under control since it had worked well in December. All hell broke loose and I bled very heavily for the next two days despite taking several doses of TXA. I went into a standalone ER on Saturday at 2am and hemoglobin was at 9, so they gave fluids and IV TXA and sent me home.

Things seemed a little better Saturday morning, but started getting heavier Saturday afternoon. I was trying to stick it out until Monday when I could call into my regular Dr for guidance, but just after midnight on Monday, I couldn't do it anymore and we went into the hospital ER. My hemoglobin was at 6. I received 2 transfusions over the next 12 hours but that only brought me up to a 6.7. Had an ultrasound that only found one possible mass or fibroid and lots of "stuff" in the uterus. During that time, I was admitted to the hospital and scheduled for a D&C and HM the following morning.

The dr only removed one 2-3cm submucosal fibroid, and thankfully, the bleeding has stopped! I have a follow up in two weeks to hear more about it, because I'm curious as to where the other one went and why this one dumb little thing had me bleeding SO badly, but I had some questions for others who've had similar experiences:

How do you get over the experience? I am SHOOK. Like, I'm three days post-procedure and was told there would be some spotting and possibly light bleeding for a bit (and thankfully there has been VERY little) but anytime I wipe and see pink, I start getting stressed. I am SO scared of starting my next period! Like, it shouldn't be for another couple of weeks or so, but I am even now freaking out about it. Like how do you prepare mentally for it to come? I've always been a heavy bleeder (and let me tell ya, those glorious months that I had my Mirena were such a great time!!) but what I just experienced was something that I never imagined could happen...and now I'm so scared it will happen again.

And for those who've had a HM that resolved a heavy bleeding issue, how were your subsequent periods? Were they "normal"...whatever that means! Is there talk of a hysterectomy? If there is a whiff of a chance that this could happen again, I'm getting that sucker taken out! We're trying to avoid it if things behave themselves until menopause sets in, but I do not ever want to have an experience like that ever again!
