Pleas check set up attempting again

A bedsheet is the best I could find I'm doing partial. I'm so scared of failing but I've got A good few hours alone. I'm worried of my knots not being good enough and waking up with my life even worse.

Someone please share advice? Does this look too risky or secure enough? I really wanna try today
