It is often time the small stuff that gets us overreactive. We already feel threatened by something that is out of our control and we are already fearful or angry or hopeless. Then the time feels pressured, and someone is asking us about something small and we overreact. We are misplacing the energy and trying to gain control over something that is important enough that we think that we have a good excuse to let out all of our frustration.
My recommendation is to separate the pile of problems into categories so that you see them as different parts and not as one large mountain. Often the truth is so simple that we miss it or we are embarrassed that it is so small and we got so reactive that we do not want to admit the truth to ourselves. Of course, sometimes we are able to laugh it off, but other times we are not. However, if we do not become honest with ourselves, then it becomes worse and we will not change.
Look within for the simple truths. The places that you are capable of changing but it’s hard to admit it because it’s so small! The small things are big things :)
The Taoists like to say: You move a mountain by moving a pebble at a time.
