Birth anxiety

Hi guys, so I have been dealing with anxiety disorders for a long time and I’m currently 33 weeks pregnant tomorrow, I have very bad health anxiety and can’t stop thinking of worst case scenarios such as dying during childbirth or severe complications. Any tips on how to deal with the anxiety of thinking worst case scenarios of childbirth.. my pregnancy has been great so far no issues or complications but yet my mind still goes to dark places fearing the worst. Any tips will be greatly appreciated.
