The simple way to bust stress is to study without giving up on things you enjoy doing.
Share few moments of togetherness with the family discussing things not related to examinations.
Indulging in simple breathing exercises- slow deep prolonged breathing just for about 4-5 minutes 3-4 times a day help to release the stress.
Thinking positively as negative thoughts can destroy the confidence. Attempt to override the negative thoughts with positive ones (forex- I study hard, I know my facts, I'll do great)
If stress really gets on their top and talking to dear ones is of no good then make use of professional help lines which are designed to help in relieving stress.
Lastly never forget that there is life after examinations.
Love isn't something you find. Love is something that finds you. - Loretta Young
