I've just watched this show and there were wildfires spreading, and heading resident's ways in hills, they try to evacuate but there is only one route out. Unfortunately, the road or bridge is blocked by the fire. People jump into a reservoir to save themselves and friends, and people drove back home hoping for god to save them. Fires took over I think 600 acres per hour, and firefighters try to battle some fire tornadoes. I think the show was called &Storm Stories& and the fire looked creepy. I think it was somewhere in California.
I think that you are just worried about your grandmother's health. She seems to be in a weakened condition. You may fear that any little action on your part may trigger a medical emergency. I would suggest that you not fixate on the fear of a future event. Instead, enjoy every moment that you can have with your grandmother while she is still alive.
uhhh make sure there is no horseplaying around where you're working, don't eat or drink anything, follow directions from the teacher and the textbook hope that helps
