Need advice- contractions!

I’m 36 weeks pregnant, and I’m having pretty regular contractions (every 5-8 minutes), I believe they are true labor contractions because they keep getting stronger and stronger and I can’t even breathe when they come. Also, when I change positions they continue.

I went to the OB today, she said I am still only 1cm dilated, almost 2 but not quite, and my cervix is super thin. She says I may go into labor soon, and to go to the hospital if I have them every 5 minutes for an hour.

My question is: does everyone feel like there is someone inside of them shredding their insides apart? I’m hurting so bad and I don’t know how to ease the pain. I’m pretty sure i wouldn’t be anymore dilated in a few hours? Any advice is appreciated. I’m truly suffering.

Edit: my water has not broke yet
