Identity crisis after diagnosis

I was diagnosed with autism a couple of months ago. I’m a 22 year old woman and truly had no idea until ahout a year ago that this could apply to me despite having incredibly tumultuous mental health my entire life and it’s honestly hilarious recounting my past self having no idea when it’s so obvious to me now. I found this all out while finishing my degree and since finishing I have just felt like I’ve lost all ability to function. EVERYTHING is hard and I feel incredibly lost and detached from the world around me. I know other people relate but not anyone I’m around a lot and so it feels so isolating, not truly being able to describe the level of self consciousness, sensory overload and identity instability im feeling. Have others had similar experiences after learning about their neurodivergence?
