Bringing up trauma in therapy

I was seeing a therapist for 6 months and then she retired. I never got the opportunity to bring up some of the traumatic stuff I started therapy for because I was too embarrased or scared. I started seeing a new therapist last week, today was my 2nd appt with her. I know I need to work through all of my trauma, but I don't how to bring it up. They're things I've never told anyone so I have no idea how to tell anyone.

Any suggestions about how to even bring this stuff up to her? It gives me massive anxiety just thinking about it, but I know it'll help me if I can just get passed saying it out loud to another person.
