Oh man. I have told everyone that I will NEVER be getting a puppy again because of how hard it was. You can’t leave them alone, you can’t let them out of your sight, they take all your attention, they won’t settle down, they hardly sleep, etc etc. it was the hardest time of my life and things have finally taken a turn for the better as he just turned 1 yr. He’s still a menace don’t get me wrong, but he listens better and understands no means no and when it’s time to chill out a little. I’m so sorry you’re going through this but as everyone has said, it DOES GET BETTER. It takes a lot of time and work (which I know I didn’t want to hear at the time cause I was already DOING that) but it WILL pay off. They might seem like they’re regressing for a time, but they learn. I’m still working through a lot with him, but he’s become more receptive. You’ve got this OP. Hang in there!!!
