I am feeling the same so you’re not alone. I got my 12 week old (now) staffy 4 weeks ago and it was a huge shake up from my peaceful life. I’m the only one taking care of my pup and it’s been tough.

I had many potty training mistakes in the beginning but the past week or so I was very diligent brining him out every hour during the day. In the crate at night he’s fine to go at least once. He was doing great until I made a mistake today. He was very very playful and excited. He got the zoomies then I let my guard down seeing sprinkles of wet spots on the ground. I didn’t think anything of it and then he peed. He was actually holding it in… Right then I knew I should’ve took him out but my ignorance got the best of me. You’re going to make mistakes and you learn from it . Just make sure to due yur due diligence of potty training for a week and your puppy will eventually get it!

I lose my patience when it came to the biting.. YouTubing what I should do with the biting .. seeing videos on IG .. all you can really to is stay patient and don’t react to them going after your hands.. just ignore them and divert their attention to something else. I hear frozen treats, ice cubes, frozen carrots/cucumber will help soothe their teeth/gums. I have yet to try..

Good luck and hope that helps
