In consequence of all this, they fall into a sad plight. For not only are they deprived of the solace of amusing themselves, but their friends are apt to fight shy of them. When people get into this state they become ultra-sensitive, and see slights and insults where none were meant. They are liable to lose their sense of humour too, and can neither appreciate nor take a joke. After that, it is not long before they see their friends deserting them, which means that they are driven back upon themselves.

That, on the top of everything else, depresses them, and they worry still more over unnecessary trifles. Probably they become sleepless, and that will hasten on as nothing else can do the inevitable climax.

Irritability of temper is often one of the first signs of this malady, not of course in those who are naturally quarrelsome, but in those who have hitherto been of a genial, companionable disposition. In fact, change of disposition is one of the most significant features in nervous breakdowns. A man who has always taken the greatest pleasure in the society of his children will begin to snap at them without any cause. Their very presence seems to fidget him.

His companions find it out, too, for not uncommonly he begins to lose his temper when he is beaten at a game, a thing he has rarely before been known to do. But what is the clearest danger signal of all is when men or women see this irritability worming its way into the solitude of their own thoughts. In one case of neurasthenia the first sign consisted of the fact that the patient found, whenever he was alone, a tendency to have resentful and bitter thoughts even of his best friends. Once or twice he even cut his chin while shaving, simply because he was feeling so angry with a chum, who had not given him the slightest reason for animosity. Sometimes it happens that a man who has not been in the habit of swearing will find himself using bad language in the course of his soliloquies. Once he starts doing that, he may know, without any doubt whatsoever, that his nervous system has gone wrong.

Increased nervousness.

Increasing nervousness is a predominant feature of neurasthenia. It appears in various guises. A man who has never found any difficulty in holding his own in his dealings with others will suddenly find himself looking forward to an interview with fears and qualms. When the time comes he may be able to string himself up to the pitch, but it will only be by an effort such as he is quite unaccustomed to, and the nervous tension will perhaps leave him spent and exhausted.

Others, who have never known the meaning of the word nerves, will feel ashamed and angry with themselves when they start at the sound of a loud noise or a banging door, or are afraid to enter a dark room.

Not infrequently it happens that people who have been the first to welcome a friend in the street will commence to make a practice of crossing the road when they see anyone approaching.

Or their nervousness may take the form of a fear of the unknown. The future becomes full of dark spectres. Visions of poverty, even of the workhouse itself, will attack a man whose financial affairs are on a safe footing. A common sign of disordered nerves is a constant dread of illness. If an epidemic of influenza is prevalent, the neurasthenic will feel certain that he is to be the next victim, and his sensations, purely imaginary it may be, will confirm his forebodings.

Loss of zest.
