Hello .....
As someones t-shirt once said .... "been there ... done that"!
I was divorced over 20-years ago - and with two daughters. I did spend some time alone in review of "what the heck just happened"! Then, for me, when the time was right, found and joined a group for divorced and widowed people that had three levels of structured support groups, monthly speakers and some degree of available social functions. It used to be called Phoenix ... and chapters were all over the U.S.
I also, at about the same time, found a talk psychologist to see on a regular basis for .... some problems with my x-wife, my father just passing away and some serious work-related problems. It was an excellent decision to see a good psychologist for their guided direction.
I can understand the difficulties in staying in a home that became a house with many previous good memories and now filled with a degree of emptyness. If it would be of financial benefit to sell - then all the better.
I have been out of work myself several times - mostly because of my profession and how it relates to recessions. I can only imagine that it was someone from work that told you to "keep your mind on the future"!
Frankly, that's a pile of crap! It may be a great "gung-ho" technique at a job when management is trying hard to push for production. But, in everyday life ...... stay in the present! It is the best way to move ahead! the best way to deal with todays' problems is to stay in today!
Again ...... a psychologist can help tremendously - and a support group should help when you're ready for one.
Stay in the present, protect your rights as a Dad, find some qualified professional help for your personal life - and with your job hunting ..... try the SBA as a start. I spent two hours or so with the Small Business Association (SBA) years ago - and the worst thing that can happen is two hours of your life spent with them. It may help to give you some direction to meet with them.
Best of luck to you. And congrats ... for reaching out!
