Today there was a very good presentation which is related to STRESS.

This is something that affects everybody sometime in their life.

Here there is some information for you to take into account:

Stress affects us all. If you can spot the symptoms, you can manage them.

General causes
Threat
A perceived threat will lead a person to feel stressed. This can include physical threats, social threats, financial threat, and so on. In particular it will be worse when the person feels they have no response that can reduce the threat, as this affects the need for a sense of control.
Generally speaking, any threat to needs is likely to lead to stress being experienced.
Fear
Threat can lead to fear, which again leads to stress. Fear leads to imagined outcomes, which are the real source of stress.
Uncertainty
When we are not certain, we are unable to predict, and hence feel we are not in control, and hence may feel fear or feel threatened by that which is causing the uncertainty.
Cognitive dissonance
When there is a gap between what we do and what we think, then we experience cognitive dissonance, which is felt as stress. Thus, if I think I am a nice person then do something that hurts someone else, I will experience dissonance and stress.
Dissonance also occurs when we cannot meet our commitments. We believe we are honest and committed, but when circumstances prevent us from meeting our promises we are faced with the possibility of being perceived as dishonest or incapable (ie. a social threat).
