So tired of being stressed

This is my last few days before I'm induced and I'm just so stressed about everything. Especially my fiances family. They're very stubborn and can be pretty rude so I am worried about them throwing a fit about some rules I have about visiting my daughter. I told my fiance that he needs to talk to them about everything before she is born, but he hasn't yet. I'm so sick of always feeling like the bad guy who is being strict and I know I have support, it just doesn't feel like it.
