Realization: Not everything is worth an ulcer, gray hairs and a bucket of tears.
When the pressure starts weighing in and stress starts to creep up on you, making it virtually impossible for you to eat, sleep and think straight, take a mental step back from the issue and stare at it. It sounds wierd because how can you stare at an issue? Trust me, when something is worrying you to death it feels as if it's a living, breathing leach attached to your temples, so treat it as such and mentally detach yourself from it and analyze the situation:
Is it life or death? Will it completely destroy your life and the lives of other people if you don't come to a decision and fix it immediately? Will stressing off of whatever it is make you a better person in the long run, or will nothing change? Are you hurting others by letting the issue consume you? Are you draining energy through negativity? Can you not possibly live life happily without worrying about it?
If the answers to these ?'s show that it's really not worth all of the damage you are doing to your brain and to your soul....let it GO.
Now this doesn't mean you have to become a total slacker and start running away from all of your problems. Just give yourself a break for awhile and tackle the issue in steps, allowing yourself time to mentally deal with everything. You'll come to more thoughtful conclusions and make better decisions if your mind is clear and semi-relaxed. Yes, stress in inevitable. But it doesn't have to be the death of you. But if you don't control it....it will be.
