This creates an inability to relax, forcing them to stay awake and anxiously think about the things they could have done differently. Overthinking is a symptom of anxiety that has a huge relation to insomnia (National Sleep Foundation, 2017). Overthinking stunts a person's ability to fall asleep because they can’t do anything but dread the next day. They worry about their future, even if it’s the most trivial things. Stress and anxiety mixed with insomnia is a vicious cycle, because the more stressed a person is, the less sleep they get and the less sleep they get, the more stressed they become.
People who suffer from panic attacks are always afraid that they will suffer from another one after the first one strikes. After their fear increases and the attacks get worse people avoid places where attacks occurred in the past. In extremely severe cases the victim may refuse to leave their house in fear that they may have an attack. This fear is known as agoraphobia. People with untreated panic attacks may have problems getting to work, or even keeping a job.
