Uncertainty

I lost my job last week. It's nerve-wracking on a good day and to most rational people. However, in the current economy, it's downright frightening. I dreaded having to tell my friends. I hated that I had to tell anyone. Most, I really didn't want to tell my oldest son. I knew he would simply have a much harder time with this than the rest of us would - because it's such an uncertain situation and he needs to be sure - about everything.

It will be hard for both of us because I'll grow tired of answering questions that I have no answers for and he will ask more the longer my unemployement goes on. They will sound like, "When will you get a new job?" or "Where will you find a job?" and "How will be pay for what we need?"
How can I explain that I simply don't know the answers to these questions no matter how much I wish I did? How can I possibly try to convince him that everything will be okay when I have no tangible proof to that effect?
He will ask more and more frequently as time goes on and trying to ask him not to and explain why will not help at all. As he both becomes more anxious and attempts to immerse himself in his trouble tyring to find a way to deal with an untenable situation he'll have to ask. He's jus tnot capable of not asking - because things change and you can never be sure when or why. We have plenty of evidence for that, don't we?
With each day that passes, he will become less and less comfortable. He'll ask more and more often. There's no getting around it. I know he doesn't mean to irritate me or point out exactly why I should be stressed

I know he means well and will be essentially thinking out loud as he continues to ask these same quesions over and over. But to me it will sound like, "Don't you know what you're doing? Anyone else would have a new job by now." or "Are you sure you're worth hiring?"
At the same time he wonders if I'm doing all I can, he'll need to know that I'm still here for him despite that I can no longer be defined by any employment. If something so fundamental can change then surely the possibility exists that other foundational characteristics can change without warning too. He'll want to know that I'm not going to focus so intently on my job search that I can no longer pay attention to him or his brother. Or maybe I'll just stop paying attention for some other reason that makes just as little sense.

He'll want to make sure I'm remaining as balanced as possible.
He'll check on me during the day from his high school classroom by sending texts, "You okay?" He's such a sweetheart. How is it the kid with Asperger's is the one who knows that this is the correct way to behave toward someone who they can't help, but they wish they could?
