Chairi/chronic pain/spinal problems

I have a chiari brain malformation. I've had decompression surgery 4 years ago but it barely helped my symptoms. My NS said it would be better for my body to have a CS because of my spinal fluid and the pressure of pushing would be major. My OBGYN sorta understands. I know this is best for me and my child but I do feel bad because I see a lot of women on here talking about natural births and water births. Does anyone have troubles with your health that influence child bearing? How do I put myself at ease? And stop putting myself down?
