Scared about c-section and epidural...

So I'm pregnant with my second my first I had an emergency c-section and scared about having another now I know I may be overreacting or working myself up but I just cant help it 😥 plus the epidural I dont want to get paralyzed please reassure me but be honest I'm trying to think positive about this but my mind wont rest (my kids will be 3 years apart when I have this one)
