Depressed for two months

I’m posting because I’m really struggling and could do with some honest advice/support.

We have a 4 month old Cavapoo called Bear, and if I’m honest I’ve had puppy blues pretty much since we got him. I feel like I’ve put a huge amount of pressure on myself to make sure he’s perfectly trained, well behaved, and doing everything “right”, and every setback feels massive to me.

I’ve taken a lot of it on mentally and it’s really affecting me. I recently went away for two weeks on holiday and felt like myself again for the first time in ages. Since coming back, I’ve crashed hard and feel really low.

The biggest issue right now is sleep. Before this, Bear was excellent at night. He settled well, slept properly, and bedtime had become one of the few things that felt under control. But since we got back he suddenly hates going into his crate at bedtime. For the last two nights we’ve been up with him for a couple of hours past his normal routine trying to settle him before we can leave him. We’re exhausted, and it feels like we’ve gone backwards overnight.

He’s also not fully potty trained. He still wees inside most days, and since we moved house yesterday he had three accidents indoors despite going outside beforehand, which feels really discouraging.

On top of that he’s bitey, jumpy, and goes wild when people come over. Lately he also seems more fearful/anxious at night than he used to be.

I know he’s just a puppy, but I feel like I’m failing and it’s taking a real toll on my mental health. Did anyone else feel like this at this stage? Does it genuinely get better? And if anyone has been through crate regression / house move setbacks / puppy blues, I’d really appreciate hearing how you handled it.
