My cognitive therapist told me as much years ago. She said there's no way to test for them in the first place. People need to learn to control their emotions and the way they think. It's a mental and behavioral issue that is dealt with improperly that causes a lot of it. Of course there are legitimate issues some people have, but generally speaking, there are a lot of internal and external influences that certain persons are ill-equipped to handle.

My first step to emotional help was God, who provided my therapist. She was great.
