Special Ed English for 2 weeks. Yikes!

I accepted a 2 week assignment without knowing it was special ed. I have not worked with special Ed students before so I’m really nervous. On top of that, I’m starting the first day of school without any lessons plans. Teacher did not leave anything for me, maybe it was an emergency that she couldn’t be here. I have no idea what to expect and I’m genuinely scared. Any tips/advice?
