Advice on dealing with stream of consciousness talking

Any advice on dealing with stream of consciousness interruption. My ADHD wife and I work together and I feel like I can barely think about what I have to do, every time Im within earshot, there's a comment, complaint, or request about what's going on in her day. 99% of those don't concern me or aren't time-sensitive, Sometimes work-related, sometimes not. I don't want to make her feel like she can't talk to me but I am exhausted at the end of the days because it takes me too much focus to do my work and context-switch all day to join in on her problems /tasks/conversation. 

Any advice or perspective is appreciated.
