Can't sleep!

I am 39+5 weeks today. Getting induced tomorrow at 6am. I could not sleep at all last night & I know tonight will be even worse!! This is my second baby. I have so many emotions going on, definitely nervous & scared. My son is 5 & I feel like I won't remember anything about babies lol. I was a single teen mom when he was a baby. & this one I am with her father so that's also different. Is it normal to freak out like this!? Lol.
