All I can say is that for AGES now you've been saying you want to do a final OE cycle.
I think you owe it to yourself to do it - and frankly, the sooner the better. Time is of the essence my sweet, and I suspect you would be absolutely kicking yourself if you missed the opportunity.
I say, do whatever you have to do to make that OE cycle happen. Then you can say you did your best, and have no regrets.
