Any other moms stay at home with their babies/kids? Do you struggle with it.

I am desperately struggling. Been a stay at home mom for 12 years (with jobs here and there but the main 12 years I've been a stay at home mom) and I just am so unhappy the last few months. It's taking a toll on me. I'm assuming it's that I'm not sure. All I know is I wake up in the morning and first thing I say to myself if dammit I dont want to do this. And it's a struggle for me to get anything done anymore. Even before i go to bed i think of how i just dont want to do this n the morning lol. Its something else.
