In general, when I'm stretched thin, small things can trigger anxiety attacks, even when I was in a good mood. For example, before I started eating better and exercizing, losing a few hours of sleep would trigger a panic attack the next day. I think the flu got you so run down, small things tipped you over the edge.
In addition, don't discount the effect that helping others going through marriage problems can have on you when you are stretched thin. Sure, sometimes helping others can be a tonic of sorts. But sometimes, there's only so much pain we can drink in before it starts to debilitate us.
For what it's worth, I was reading the Gospel of John this morning and I was looking at Jesus' discourses in chapters 14-17. I was struck with his desire for us to experience the joy and intimacy he has with the Father.
