I feel it too you are alone!! I was like what in the crap am I doing, can I handle this, I just take a minute, breathe and remember how strong I am!! I am doing it alone and I get overwhelmed and scared but it is going to be ok. And you are going to be ok too!! I just want you to know you are not alone. I am scared too!!
You will be fine get the epidural and you wont feel anything. I honestly didnt feel a darn thing and after my son came out i felt like a million bucks. I am in baby #2 due in 38 days and i am not scared. You will do fine. Just relax
Push the risks out of your head. If your pregnancy has been low risk, don't stress yourself over outcomes that aren't likely. Remember that modern medicine is highly effective at minimizing risks and being prepared for any spontaneous ones.Don't ask what could go wrong or go looking to find out because then you're definitely going to cause unnecessary stress to yourself and baby.
As for the pain, there are many management options. I got an epidural with my first and barely felt a thing until they turned it off so I could push. I'm going natural this time, but the epidural made me not feel a thing for most of my labor. You can switch positions, try breathing exercises, have someone massage you, take a warm shower, get actual pain meds in an IV. There are a whole slew of things. You'll be fine.
