You're allowed to be in a funk. It's ok. I know we sometimes feel guilty that we're in a place where so many others on this board want to be, but that doesn't mean it's easier. My friends from here who I'm in touch with in the alt are all headed/have been down the D path. I worry that they resent me/my sitch but honestly they've all been very supportive and great.
Re: the work sitch. You're right, dwelling on it won't make it any better. I think H might feel better about it if he has a plan if/when it comes out and becomes a problem. So help him work on a plan if he asks and let him know that you will be there to support him. But also take care of yourself and don't let it bog you down.
I'm not a parent so not sure what to say about S18. I know you want to take away all the kids' hurt, but perhaps the best thing you can do is show them by example that life is full of obstacles to overcome and you're doing just that. Again, those are the thoughts of someone who is happily childfree so keep that in mind.
Try to do something fun this weekend to remind yourself that it's not always going to be gloom and doom.
If you love somebody, set them free. http://tinyurl.com/2empx2g
