Hello,

Last week, I was diagnosed with ASD and obviously this is a massive adjustment to try to process. I struggle in busy, overwhelming environments and I'm wondering how I can make this process a bit easier for myself. I wear noise cancelling headphones which help me massively as well as using fidget toys, but I still don't feel like people around me understand or can tell that I'm visibly struggling.

Is it worth me getting something like a lanyard? Or does this draw too much attention to myself for no reason?

I hope that someone can point me in a good direction, I feel so lost since the diagnosis and have no idea how to move forward.
