Ok can I just add some positive encouragement here? 
We had our working cocker boy from 10 weeks. He went straight into a puppy pen in the kitchen. We ignored any whining in the night for a couple of nights and then he was fine. We put down lots of paper in his pen and made sure we let him out for a wee last thing at night and first thing in the morning. Obviously there was some mess on the paper for a while but nothing that can't be cleaned up.
He never really got into chewing, perhaps he just wasn't the breed to do so.
He cost £500 to buy and a few quid for innoculations, toys, lead, bed, etc.
I spent many happy years taking him dog training. He got it down pat very quickly but I found I enjoyed it so much. We did obedience, agility, our dog club did shows and fun days and sponsored walks, it was lovely. He is now a brilliant little dog that can go anywhere and behaves himself impeccably.
We did some gun dog training because we use him for picking up and he loves it as much as we do. To see him hurtling across a field, to the exact spot where a bird fell, finding it and hurtling back with it to sit proudly with it at your feet, is brilliant. And we've had so many comments on how well behaved he is because of all the obedience work we did.
We have some lovely walks across the fields behind our house. Obviously they need a walk even when it's raining but on a sunny day when you're surrounded by stunning scenery, it's great. It's Mummy's time out.
And then we come home and sit by the fire and he curls up at my feet.
When I come home he's always there, wagging his tail, usually with a shoe in his mouth because he can't greet anybody without something to present (gun dog genes!). He follows me round the house like a shadow. He barks whenever somebody comes to the door thereby scaring away any potential burglars (hopefully).
He's my Boy. I have often been heard to remark after some particularly demanding childcare, 'I should have stuck to dogs!' He's always there for me, I love him to death and I wouldn't be without him for anything. He was practically my first child.
He's My Boy. That's it really.
I hope you enjoy your dog as much as I've enjoyed mine.
