Does it get better? I feel like I’m loosing my mind?

I’m loosing my mind. My puppy is making me question my choice.

I brought home a 9 week old American Cocker Spaniel puppy last week on Tuesday, and I feel like I’m loosing my mind.

We immediately got to outdoor training, and crate training him. He had that down well for the first two days, then last night he started peeing in the house (even after we’d take him out) as well as pooping indoors. He also seems to resist sleeping in the crate when we’re home but will willfully go into it and sleep while we are working. If we’re home and he can’t physically see us he barks, the whole damn time.

I couldn’t take a shower today without just putting him into the shower with me, because he just wouldn’t stop barking the whole time. My other pets seem ok with him now, but still standoffish.

When I enforce naps he barks for 40 min. He’ll only sleep during the daytime but is so resistant to any naps from dinner to bedtime.

I know I already have the puppy blues, but I feel like I’m doing everything wrong. I try to figure out answers online and immediately feel like I’m causing my puppy to have separation anxiety, or regress on his toilet training because he isn’t doing as well as the dogs trainers on Instagram say they should be.

I’m doing everything I’m told I should. He go for car rides, he’s been in the stores in the buggy to socialize him. He plays independently, and can sleep for almost 3 hr stretches (usually it’s no more than an hour and a half at a time though). We do enrichment and training and we’re signing him up for puppy classes.

People have had dogs for centuries and yet I don’t feel like they felt this way, or as much thought was put into their dogs!

His only saving grace is he only gets up twice during the night. And he is very smart and has picked up things quickly. He’s just suffocating me right now. Is this normal?
