OMG, here we go again, getting away from the issue and making it personal. The OP asked for advice about helping with an issue. She is asking how to make it (the crate) a little more acceptable to her dog, which she actually loves very much.
To the OP, sounds like she has separation anxiety. Since you have stated that even when looked after by others, she sits by the door, or constantly looks for you, maybe you should try the DAP or a rescue remedy type of option. I myself have a girl that has separation anxiety, she has come to the point where I don't crate her in the house as she doesn't just whine and cry, she looses control of her bowels and will literally spin in her poop and throw it everywhere and make a huge mess. Then she gets herself into such a state where I think she could have a heart attack. So, I just don't crate her in the house. She's fine in the car or a hotel room, just not in the house.
I, personally, would start to work on leaving her alone for a few minutes at a time, outside the crate, when I went to do a short errand. Such as walk to the end of the drive, outside for a 1 minute break, etc. then increase the time. You might find that if you start small and extend the time, she will be less destructive.
For the europeans, I agree with less crate timing, but sometimes it's just not a reality here. While we do have some options in doggy daycare, sometimes the way things are set up at the daycare, (and they are not on every street corner here) it's more detrimental to the dog to take them there than to go it alone. I've seen some of the daycares here and I wouldn't even bring a mouse here the way some of them are run. Add to that is the cost. I believe some of them are way out of line on their prices. $100 bucks a week when your pay is only 3 to 5 times that amount is ridiculous. So other options must be found.
Add to this, some dogs love their crate. My other girl starts to run circles in front of her crate about 9pm and INSISTS on going in her crate then until the am. There are just some dogs that are this way. I hate putting her in there, as I would prefer to leave her out, but SHE wants to go in there. I have tried to leave her out and she just continues her pacing until the crate is opened.
So, take heart and try a few of the options mentioned here. It just might help with some of the anxiety.
