Stress can and will utterly fuck you over. For some things, think about if there's even anything you can do. If not, try not to stress over it. If they want $160,000, and you know you can't pay that shit, then try not to stress about it. Find someone that knows about that stuff, and ask him what you CAN do. There are numerous consumer advice boards where lots of knowledgeable people/professionals in that field volunteer their time to help people out (kinda like Rip come to think of it). They're not going to "take your case" but they could give you options and point you in the right direction.
If it's something you kinda do have control over, like your job, then it can be a bit more difficult to cope with, imo. On one hand you feel you're more valuable than that and could work towards something better, but on the other hand it's a little difficult to just "go and get a better job".
Whatever it is, decide that you can set it aside, at least for decent chunks of time in the day/week/year, and just focus on something more productive.
