Im so scared of labour what can I do?

Hi, im currently 41+2 pregnant I had a membrane sweep on Monday, Ive had cramping on and off since and today I lost my mucous plug. Im also booked in for an induction on Friday, and being given a time and a date terrifies me, following my internal exam on Monday the midwife said they will probably just break my waters then use the IV drip if required, I dont think Ill sleep a wink Thursday night even though I know its really important I do, At least if it happens on its own its outwith anyone's control then fine, I can spend as long as possible at home etc. I was induced before, so now I know what to expect, but thats the bad thing! Last time my waters broke and showed meconium (my baby had pooped inside me) but I had no contractions so was induced with IV and the pain was immense I needed a epidural at 3cm dilated! The whole labour lasted 23 hours, I was bedridden throughout as I had so many tubes and things (drip for inducement, drip for fluids (as I had a fever), a catheter, epidural tap, l probe attached to baby's head to monitor heartbeat) needed an episiotomy and forceps at the end, followed by a blood transfusion for low iron! The epidural worked well but I had constant back pressure pain, not sure why as baby wasnt back to back. As time closes in Im really getting scared and panicky, any ideas on what I can do to stop worrying as much? Thanks!
