Uncontrolled brain and constant thinking are manifestations of anxiety disorder. Anxiety disorder is a very common mental disorder, more likely to occur in people who are under stress and live at an excessively stressful pace. You need to go to the hospital to improve the anxiety scale related assessment, and if the score is higher than a certain level, you need to take oral anti-anxiety medication. In addition to uncontrollable thoughts in the brain, there are often irritability, fear of noise, easy to lose temper when things happen, as well as difficulty falling asleep and excessive dreaming during sleep. Commonly used anti-anxiety medications are buspirone and doxepin, both of which are used during the day. Doxepin side effects are mainly sleep-causing and sedative.

It is important to pay attention to self-regulation, try to reduce stress, avoid too much stimulation of environmental factors, and patients with conditions can go to the local psychological hospital for outpatient psychological counseling.
