hi all completely new here, not sure what to say don’t want to sound like I’m moaning

I am a full time carer for my husband who has chronic back pain, has a lot of bad days so spends a lot of time on bed on morphine. He also uses a wheelchair to get around. We also have 7 children

question is I am feeling so overwhelmed at the moment he jokes a lot about me not getting him enough stuff eg if the children have had the biscuits out how come I didn’t take them upstairs for him too ?? And he doesn’t think I’m working enough for the money I’m getting for being a carer!? So I don’t understand what is a role for a carer, I give him his medication, breakfast lunch and dinner and do all duties a wife does cleaning washing etc.....
