Overwhelmed with DID diagnosis and seeking advice

I'm Kayle. I think I may have did or osdd. I've known about my cptsd for a long time, but the did is new. I started connecting the dots earlier this year, and now I'm completely overwhelmed. On one hand, knowing and talking with my parts is creating a more cohesive system. On the other, it's like there's a safe space to speak and now everyone's yelling. I'm learning about abuse in my youth I didn't know about, On top of the abuse I've been working through for years. I honestly thought I was done with surprises. Anyways, I guess I wanted to ask how to go about getting diagnosed. I'm scared because my doctor is new and skeptical, and I've never seen a psychiatrist. Some of my parts think we're faking, and shouldn't bother, while others are begging for help from a professional. I'm all turned around, and so intimidated by the process that seems to be ahead of me. honestly any advice is appreciated.
