Anxiety is killing me

If I didn't know my husband as well as I do id think he was making me anxious on purpose.
But the truth is that his brain runs a mile a minute and he can't help but plan for all the many (however unlikely) ways in which any given situation could blow up in our faces. He has to run through everything I do and point out all the things I could have done different and arguably better, and why what I did was short sighted and could come back to bite us in the ass....
And I'm left feeling like a idiot who never learns and always does the wrong thing
But he honestly is just someone who never stops analysing and planning and so on
