From Integrated Health Information Systems Pte Ltd:
Stress is not always caused by situations. Often people create their own stress by having negative thinking. Negative thoughts do not only lead to unpleasant feelings, they also reduce the quality of your performance and undermine your working and social relationships with other people. They are also commonly associated with many psychological disorders. Hence, it is important that the negative thoughts are challenged. "Thought Buddy" is an app which helps you manage unhelpful thoughts and build a helpful thinking style.
