Need advice on labor please

Priscilla
I had a c section with my 1st kid and now it will be almost 5 years when I will deliver this baby. My doctor told me that I will be okay to do a trail labor which is where they try to do a vaginal birth and if anything goes wrong they will just c section the baby out. I'm so scared to deliver the baby vaginally just because I have only had a c section before. Im worried that the pain is just going to be so horrible vs a c section where I take a pill to help the pain in my own home. I'm also scared of ripping down there... One more thing is my iron level is at a 9 and it suppose to be a 12. Since it is a little low I see stars sometimes depending on the day. So I'm worried that I will feel dizzy while delivering. How bad is delivering the placenta? One more thing, since I already had a c section there is a small chance the baby can go through the area where they cut me open and the baby will die or have nerve damage if that happens. Idk what to do and I'm very indecisive with this decision. Please give me your advice!! My doctor told me that my chances are about the same with either one and it's pretty much up to me.
