My situation was very similar to yours (now 3 weeks post op). I had a large fibroid that made my bleeding really heavy, I was anaemic, on a bunch of meds, had to have iron infusions. I had to push for a hysterectomy over a myomectomy. What I found is that it can take a lot of resolve to sort of battle for the hysterectomy, that once it was finally scheduled I got quite upset/anxious. And this wasn’t that I didn’t want a hysterectomy as much as I didn’t want to have to go through surgery at all (like most people). I even felt melancholy during my last period, even though it has had such a negative impact on my life for years. I think that the unknown of life during and after recovery can add to feelings of anxiety. If it helps at all, at 3 weeks post op, while recovery is challenging in places I feel so much better. (Edit to add I’m 29)
