I'm sorry to tell you but often, it doesn't get any better and surely doesn't get any easier while they are away. But, you can and have to change how you deal with it.
There will be other hurdles down the road ahead, be prepared.
If you are able, take a vacation this weekend with family or friends who have moved away (BUT DO NOT SPEND YOUR TIME WIDDLING OVER THIS). A nice 3 day weekend away from everything can work wonders. And, change things around the house a bit and create a different feel. Paint a room (it's much cheaper than a therapist ). Once you start occupying yourself with things, you will be surprised how even if just a little at a time, you will be refreshed and clear headed.
