Wow!
I used to have a friend who had access to brick cannabis. I want to say it was likely Mexican sativa but I don't know for sure. It would come looking like a pressed brick of plant matter that would turn to powder once broken and was full of seeds. Anyways it was super cheap like 300 for 4 ounces cheap.
I would put an ounce in a batch of brownies and many of my friends failed to heed warnings because they knew what the cannabis looked like. However one by one many of them would come back saying it knocked them out and sent them to bed.
Sometimes you just need to have someone else there to force you to move around.
Sorry about your father. That is a scary thing when it happens. You aren't going to die (medically it's been shown to be very hard for cannabis to kill you), but during a cannabis edibles overdose...it really feels like you might.
