Welcome back, Rob. I'm truly sorry about the bad news. I recently (April) took the SP and also found it significantly harder than the R/S.
I just went through a job change, and had to postpone studies, but I'll be re-scheduling before the end of year. As soon as the new CCO account kicks in, I'll be posting with a new ID.
I am not looking forward to the SP pain again. Are you going to re-take?
