My partner with anxiety often gets what he describes as ‘stuck.’ He says that he doesn’t know what to do, doesn’t want to do anything, but doesn’t want to waste time not doing anything. So he sits there doing literally nothing, locked in, like a statue.

He says he wants me to help him to start to do something, but generally says no to anything I suggest, is reluctant to joining in if I start something we could both do, but gets annoyed and argumentative if I run out of ideas or leave to start something. 

Does anyone have any suggestions as to why he occasionally experiences this and what I can do to help him feel better? He himself is struggling to understand this. Thanks
