Feeling burnt out and don't know how to talk to my wife about it

I work full time, she works part time, but somehow I still feel like she's doing more with the kids. I'm exhausted all the time and when I get home I'm just spent. I want to be more involved but I also feel like I need to provide financially. She gets frustrated that I'm not doing enough around the house even though I'm trying. I don't want to seem like I'm not pulling my weight but I'm genuinely running on empty. How do other dads handle this conversation without sounding like they're complaining?
