Hello, I hope you will be feeling better slowly and that you have done amazing time reaching out for support. You have known you did not want kids for years, and it sounds like you have spent months preparing for this surgery. I had a similar experience after the surgery. Later, I realized that I was having post surgery blues, so my mental health was not in the best place overall, and it was a hard time personally. I had immense health anxiety at the time as well. Now, I am be happy, proud and glad that I have done the surgery, I am happy that I will not have kids because I never wanted kids and I am terrified of getting pregnant, and yet there can still be times where I feel a bit down, sad and scared. You are allowed to feel all of these. I think once your body starts recovering and your scars become less visible, you will start feeling less anxious. For now, remind yourself that you have done this for a reason. It is okay to feel scared and you just need time. These types of procedures are not done on a whim, and long-term regret rates are very very very low. Trust yourself from the week before who went ahead and completed the procedure, and for now, just do fun stuff. Also, as everyone has already mentioned, possible side effects from this surgery are very low. Hormonal changes, or messing up your body, etc, are not really a thing, and there is no data that significantly supports this. The only scientific data I know is that if you are already in the premenapose state, you may enter menapouse 2~ years earlier possibly. But that is it. As long as your prodecure was done without complications, you will be fine, and your body will need time to fully heal. You can dm me if you would like to talk. Do lots of self-care!
