Finally opening up about it

Hello guys, I'm a 19-year-old girl that finally found a name for this condition. I feel so comfortable and happy while I pretend and act as a different person. Sometimes I'm a character from a movie or tv series, sometimes a singer, a k-pop star, or even a cooler version of myself.

I started therapy about 2 months ago, but I will finally open up to my therapist on Wednesday when we meet. I also suspect I have ADHD, but I don't wanna seem like I'm self diagnosing to her, so I'm really afraid of how I'm gonna tell her.

I'm really happy to have found this forum and to know that a lot of people are going through the same situation as me. It's embarrassing, scary and good at the same time, but I'm decided to at least figure out who I am first.
