How can you tell if you or someone close to you is suffering from high levels of stress?

Samaritans say signs to look out for include:

Being withdrawn or unsociable

Being low-spirited or depressed

Drinking alcohol excessively or becoming dependent on drugs

Finding it difficult to relate to others

Taking less care of themselves

Acting out of character

Feeling less energetic or particularly tired

Being irritable to excess

Finding it hard to concentrate

Eating much less or much more than usual

Putting themselves down (self-mockingly as well as seriously), for example "nobody loves me" or "I'm a waste of space"
