What are the dangers of a C-section?

Dear Doctor, I’m 27 years old and pregnant with my first child. I’ve heard so many ‘horror’ stories about natural child birth and now I’m thinking of opting for a C-section. I know it’s also not easy but after a friend of mine told me how she ripped while trying to give birth, I’ve been scared. My mum tells me she can give me local medicine to strengthen the muscles so that I won’t rip. Is this possible? Is there anything that can actually prevent tearing? I would really love to have a child the natural way but I’m terrified.
