Stress stress stress

This is the first time in my life that I feel so stress studying.
Which subject? ACCA F8

I just realise that I don't even know how to do questions start with

"AUDIT PROCEDURES/SUBSTANTIVE PROCEDURES"

I have nightmare for two nights already. I was reading F8 textbook in my dream and all the audit terms come out. When I open my eyes, it's already morning. I can't sleep properly!

I never thought that this will happen to me. I used to be very relax in study. Never force myself to work extremely hard. Now, I don't know what to do.

I started to feel a little bit regret for choosing ACCA.
