I’m sorry to hear about this too. The best thing to do is to try to look at it calmly, and just take things as they come.
I know exactly what you’re going through though, because a case I argued on behalf of my parents took 2 years to resolve, and a lot of stressful things happened during that time (the case involved opposing a developer who wanted to develop the property next to my parents’ house). I know its really hard not to worry, but try to think of what advice you would give a friend who was going through the same thing — and then take that advice yourself. 🙂
