Stress is usually seen as a noun, ie something you have got, like an arm or a leg. But stress isn't like that - it isn't an identifiable thing that can be removed and taken away. Stress should be seen as a verb, ie something that you do. We are doing it to ourselves even if it's automatic and we're not aware of it. Pretend for a moment that stress is just our body's way of telling us to slow down or to change something. Being stressed is about doing things such as hyperventilating, sweating or tensing up. These are all actions, or rather reactions that your body and mind have to excessive pressure.
It follows that if stress is something you are doing, then you can choose to do something else. Rather than worrying or tossing and turning at night unable to sleep, how about dong something different as a reaction.
Stress is a medical condition and it can have a serious effect on your health. If you think you are suffering from stress it is crucial that you consult a medical professional.
