2nd baby and afraid of labor

i dont know what is going on with me! I am pregnant with my second boy and I am honestly TERRIFIED of giving birth I don't know why I am thinking all of the bad things that can happen . with my first I was ready I took it like a champ but with this one I feel like "omg what if I need a csection" or "omg what if nobody is home when I go into labor" " when they took out my placenta that hurt me more then the actual birth " or "how will I put them both to nap how will I handle a toddler and a newborn "like I am so scared of all of these things !!!:( anyone else going through this as well ?
