I have sent an email to the one I see that says these are what needs to be addressed. That way I did not have to get through the 20 minutes or so of crap and it could get started. For me, the worry around it and the aftermath of I wasted time again, would be worse than diving in. Not diving in seems to add stress and tension and it sort of seems like it could be for you too - it is on your mind, plaguing you. If it is too much, you can ease off, but give it a go would be my suggestion. It will not be fun, but you are not having fun now either.
