I regret getting this puppy

Later edit: THANK YOU SO MUCH EVERYONE! It was so good to hear that this will end sooner than later and that it is okay to have her in her playpen even if she cries. I started her on the 1 hour up, 2 down schedule and it is SO much better! I appreciate all of you immensely!

We got a 8 week mini Schnauzer last week and I'm already regretting it. She sleeps great, she's potty training great BUT I cannot get anything done (I work from home). I spend 90 minutes with her (I take her outside, train her, play - feed if it's meal time, take her outside again) and then I crate her for 90 minutes, rinse and repeat. It's getting frustrating because I literally do nothing but spend those 90 minutes with her, then hurry to get stuff done in the next 90 minutes and my work is suffering, my kids don't get our usual time together, my household chores are on the back burner... How do you guys do it????
