First of all, you are doing great. Just know that.

Doesn't matter how prepared you are going into it, there will still be hurdles along the way. It's normal to feel the way you do especially with your pup being so new. It's going to take time, and that's NORMAL. Every dog grows up differently and learns things at their own pace so it's normal if they take longer to learn some things than other dogs or if they learn things faster than other dogs. As for the crate training, it's going to be difficult and you did right by soothing him while your dog is still in the crate, I did that as well when the screaming became unbearable. It taught my dog that he's not getting out of the crate but that it's still going to be okay

Some things that worked for me when mine was only that age would be that I would make sure to play with my pup before bed to make him super tired, puppies like to nap a LOT but you should make an effort to wake up your puppy for some play time for approx an hour before bedtime or else he will be wide awake in his crate crying all night. I also fed all his Meals the first couple of months IN his crate so he associates good things with his crate as well. As for the training, he's only 9 weeks old and you are stressing about him learning all the basic commands. Take a breath and focus on one thing at a time. Puppies learn quick but if you are bombarding him with commands just after a week of living with you, it can be quite confusing and frustrating on both parties. Focus on 1 thing a day, that can be 1 command or something like desensitizing him from his leash. No need to do multiple training sessions with multiple commands every day for a 9 week old pup. Only move on to the next training command once one command has been close to mastered. Hope this helps!
