Part of me agrees with Laeh, and part of me agrees with Marla.
I had been well educated prior to my births about natural birth. My sister was a homebirther, and she was also a child birth educator, so I got to learn a lot of things, whether I wanted to or not (hehe!). I still didn't fully get it until I became pregnant and decided I had to research it to see if my sister was a little crazy or if there was something to what she was saying. Turns out there's so much EVIDENCE that birthing with a midwife has way better results (main way to truly have a natural birth since many doctors don't know how). So, I chose a midwife at a birth center.
That was a long and hard birth. Baby was in the birth canal for close to three hours (pushed for three hours). It did a lot of damage that took a LONG time to heal from. I also had some bleeding issues (lost 2 liters) and overall it wasn't the birth I was expecting at all...though, I did L. it. It just wasn't that birth I hear people talk about when they talk about natural birth!
My next baby, I felt like the hospital was the way to go. (my first had to be transferred for open heart surgery, which was very stressful!) He was huge. 10 lbs 11oz. The doctor I chose was very natural birth friendly. I had him vaginally. I tore - she didn't do an episiotomy but provided perinneal support instead. He was in the birth canal for about 45 minutes. That made me really, really sore after.
Next baby, back at birth center. Besides the fact that she felt like a spiked bowling ball on her way out, she shot right out (10 minutes?) and healing was MUCH faster (finally!).
My last baby had to be a c-section due to a complete placenta previa. I was very scared of having a c-section. Who wants major surgery?! But I knew in my case, there was no question as to whether it was needed. Not only did I have placenta previa, but when the doctor got the baby, she said there was a knot in her cord, the cord was wrapped around her neck, and it was a short cord. Individually those things usually aren't big deals. But put them all together and that would have been a bad vaginal birth...
So, guess which birth was the easiest to recover from?! The c-section! The other births (minus #3), I was still sore at 6 weeks. And after my vaginal births, the pain could easily be described as excruciating for a while afterwards. I was so swollen and sore.
What you've gone through isn't normal. The doctor very, very, very likely caused all that damage DUE to the episiotomy. It's so dumb they do them! But since he did, it could very likely mean more tearing in the future. And some women do tear easily. A c-section is not awful. What you have gone through is. Healing with my c-section was amazing. I couldnt' stop telling me mom how awesome it was to not have a sore bottom. I could actually SIT. I could walk almost NORMAL. The pain didn't compare.
I always hear how c-section makes it harder to take care of your baby afterwards. Not true with me. It was SO much easier to care for baby after my c-section. I don't have typical vaginal birth recoveries. I could hardly walk for days. I couldn't pee from being so swollen. I couldn't stand and shower. Most other women I know heal MUCH faster after their vaginal births than I have...but you are in the same boat as me. You didn't have an easy vaginal birth recovery. There is nothing wrong with choosing something that will damage you less. So many people get stuck on hating c-sections, but sometimes they really are helpful. Who wants to be damaged down there like that?
So basically, decide what you want. I loved my natural/vaginal births. They changed me as a person, and I am forever grateful for them. But I loved the healing from my c-section more than I loved the healing from my vaginals! And I NEVER EVER thought I would think that. I was so anti-csection (for me) prior to that...I had a similar view to most of these anti-csection ladies. But after experiencing it myself, I see huge benefits of them. What you went through with your tearing was way more painful and worse than the typical c-section. The question is whether you would tear without an episiotomy. A little tear (that naturally occurs), like i had with my giant baby, heals better typically and is less of a tear (by far) than an episiotomy. But some natural birthers have horrible tears, it's just QUITE rare comparatively. You've gone through something that has taken years to heal from. You have to decide what you want. There is nothing wrong with either choice. I loved all my births - none were a "dream" birth - even loved the c-section, ESPECIALLY the healing part.
