DISCLAIMER: I have no professional qualification for this statement, it is just an observation from my own experiences.
I think lumping all problems into one category is the first mistake. If you say to yourself "STRESS is going to eat me alive", all stresses become equal. Then, even the little things can carry a weight which will crush you. So, first you must decide what is bearable and what is not. In other words, you must prioritize the problems you need to fix. Most of the little things can either be fixed or acepted, you just have to face them one at a time. Many of the larger things can also be fixed (athough some may take considerable time and effort), and some will just have to be accepted. In short, there is no easy answer, things go wrong in this world, we just have to fix or accept them one at a time. Jeremy
P.S,
Reaxation techniques like controlled breathing will help you calm down enough to analyze your problems, but "STRESS" will not go away until you fix or accept them.
