I have recently discovered that I may have anxiety, but I'm not sure.?

Ok so a lot of stuff has recently plumped down on me and it all built up on Christmas eve. My parents just finalized their divorce and I'm 17. I was playing a game with my friend and then I had this fleeting thought of "What if everything was a dream?" I started having some sort of panic attack. I feel much better after talking to my mom about it and she scheduled me for a talk therapist. I'm just worried about my mental condition. Am i crazy for asking such things? I just want some extra input. My mom doesnt think i have anxiety/depression but the stress of everything has been steadily pushing me down. I don't feel like myself. I don't know if anybody will get this but I want to feel like myself again. Sometimes I close my eyes and think of days when everything was good. We lived on a ranch and i played with friends and was able to just hang out with my parents. We suddenly moved up to the city and i went from 7 people in my grade to 400+. It's all so bitter.
