Growing numbers of people are becoming addicted to text messaging（手机信息）, a German doctor warned recently。
Psychotherapist(采用精神疗法的医生) Andreas Herter estimated that there were some 380,000 sufferers in Germany。 Herter based his prediction（预测）on the growing number of manic mobile phone users among patients arriving at his Hanover clinic （诊所）for addiction treatment。
“Text message addiction is a real and serious illness because it causes mental and financial damage,” said Herter。 “The problem leads to depression and personality disorders, not to mention skyrocketing （飞涨的）phone bills。”
For example, a teenage boy spent 8,900 euros (US$11,000) texting people he didn’t even know and a married couple could only communicate by text message, even when they were sitting side by side。
