Wife thinks I'm being lazy but I think I'm depressed

We keep fighting about chores and me not doing stuff around the house. She thinks I'm just avoiding work, and maybe I am? But I genuinely feel like I don't have the energy. I wake up, do work, try to be present with the kids, and by 8pm I'm completely fried. I suggested seeing someone and she was like "oh so now everything is a mental health thing?" which... stung. I'm 42, we've been married 11 years, and I feel like we're not even communicating anymore. Not sure if this is relationship stuff or depression stuff or both. Anyone been here?
