We have the same thing going on with DS10. It comes and goes, but we're in the thick of it again, currently. I don't really have any advice, so I'll be watching this thread with interest. One thing that we do is to tell him that there isn't a "wrong" answer to whatever choice he's having a difficult time making. Sometimes it helps, sometimes not, but I want him to see that these types of things aren't life or death, and therefore, aren't worth the stress he's causing himself (or us). IOW, if he can't decide between chicken nuggets or a burger, I remind him that I'm pretty sure he'll have an opportunity to choose the other one at some point in the future.
I'm hoping it gets better with time.
