Kiya - GOOD for you for asking for the accommodation. What is, is. What happened, happened. It wasn't your fault then, and it's not your fault now, and it's empowering for you to look out for yourself now. And asking for the accommodation is a way of looking out for yourself. If the class ends up being too much, it's OKAY.

I think you're doing great - trying so many new things right now. Be kind to yourself. You deserve it.
