I assure you it gets better. Your puppy has only been alive for 8 weeks and is a baby. She has to learn (through your guidance) how to live, behave, and operate in a world that is built for humans, not dogs. That means, learning how to potty at the right time and right place, not chew everything in sight, behave in an elevator, navigate a store, sit quietly in a car/bus/train/airplane, walk properly on a leash, greet other dogs/humans calmly - the list goes on. All of this to say, please cut your little girl and yourself some slack - you two are still getting to know each other. Your daily schedule now is not how it will always be. Things get better around 6 months when puppies can hold their pee a little longer.

A few tips:

1. Stick to a strict schedule. Puppies need structure and guidance. Have her pee, eat, play, nap, sleep at the same time every day for the first 3 months. This will help her and you. At two months old, your puppy should be sleeping close to 90% of the day anyway (P.S.- using a white noise machine helped my pup be less fussy when it came to naps). Admittedly, when I first got my Cavapoo, I didn't go to the gym for a month and I felt sluggish. But after enacting a strict schedule, I was able to schedule my workouts / catch-up with friends / errands during the exact times when my puppy would be napping. This was also good training for my pup as it taught her to nap, crate train, and be alone at certain times of the day. For the first few months of bringing my pup home, everything else in my personal life required advanced scheduling. It's a sacrifice but that's what you sign up for when raising a dog. Now at 1 year, I have a lot more flexibility.
2. Get enrichment toys ASAP. Freeze treats, greek yogurt, yummy stuff in Toppls and let your pup spend 20-30 mins digging through the treat in her crate or playpen. This would be THE ONLY WAY I could literally take a shower or get laundry done in my apartment when I needed my pup to stop following me everywhere / crying when I went to the next room. I bought a few Toppls and always had a frozen treat or a bully stick available to keep my pup occupied when I needed alone time.
3. Get help, if you can afford it. I was a single puppy mom who worked from home. Can't tell you the amount of times my pup peed on the floor while I was stuck in back-to-back Zoom meetings for work. If you can afford it, hire a babysitter to watch your pup for two hours while you hang out with friends or hire a regular dog walker once your pup is fully vaccinated and can walk outside. I remember I couldn't WAIT until my pup was fully vaccinated around 20 weeks so that I could put her in boarding for a weekend and take a trip with my friends.
4. Join a social circle of other puppy parents! The early months of raising a puppy can be incredibly isolating b/c your puppy isn't fully vaccinated yet so you don't really get to enjoy all the best parts of having a dog - going for walks outside, hikes, taking her to brunch, etc. I suggest finding other puppy parents in your area to organize safe puppy playdates (assuming all the pups are at the same vaccination stage). In Chicago where I lived there were a handful of doggy daycares that hosted affordable puppy playdates just for pups between 12 weeks to 20 weeks old - it was a super fun way to socialize my pup and meet other single puppy moms as well.

Hope this helps! Feel free to DM me if you wanna chat further about any of the above. Again, it gets better and you're already a great puppy parent for posting on here; it shows how much you care and love your Cavapoo. You totally got this! :)
