How can I make partner understand how I feel?

I know we all know how exhausted we constantly are, and how useless we feel in not being able to do even half of what we have always done. But how can I make my parter understand?

This weekend we have worked in the house, I have done as much as I possibly can including helping to move furniture around (which I shouldn’t be doing). This afternoon he has had a dig at me for not doing enough and that he feels like he has done everything and I haven’t pulled my weight.

I may not have been building furniture like he has, but I haven’t stopped.

I already feel useless as I am usually very hands on and able but after having to go into hospital the other night for reduced movement it has been a wake up call. They told me to take it easy and consider that I am doing too much. HE HEARD THEM SAY THIS!!

Sorry for the long post, but I am at such a loss at the moment I feel so sh*t 🙁
