I am very scared and very confused.

I feel very nervous. Somewhat scared. I'm unfamiliar with this school, and some of it makes me feel like I'm being lied to. That might just be anxiety talking. My mother has been a witch my whole life, and I've only noticed after realizing I was one myself. This school seems to have an understanding of what I mean by that so I don't think I have to explain that no, not like in Harry Potter. I'm a bit confused about what I'm supposed to do from this point. I am Autistic, and new things, such as a new school, are hard for me, so I usually await specific instructions.
