上個星期，懷疑自己患上了輕微‘強逼癥’。。。OCD- Obessive-Compulsion Disoder

Obsessive–compulsive disorder (OCD) is a mental disorder characterized by intrusive thoughts that produce anxiety, by repetitive behaviors aimed at reducing anxiety, or by combinations of such thoughts (obsessions) and behaviors (compulsions). The symptoms of this anxiety disorder range from repetitive hand-washing and extensive hoarding to preoccupation with sexual or aggressive impulses, or with particular religious beliefs. These symptoms can be alienating and time-consuming, and often cause severe emotional and economic loss. The acts of those who have OCD may appear paranoidand come across to others as psychotic. However, OCD sufferers generally recognize their thoughts and subsequent actions as irrational, and they may become further distressed by this realization.

While some with OCD perform compulsive rituals because they inexplicably feel they must, others act compulsively so as to mitigate the anxiety that stems from particular obsessive thoughts. The sufferer might feel that these actions somehow either will prevent a dreaded event from occurring, or will push the event from their thoughts. In any case, the sufferer's reasoning is so idiosyncratic or distorted that it results in significant distress for the sufferer or for those around them.

Compulsions include counting specific things (such as footsteps) or in specific ways (for instance, by intervals of two) and doing other repetitive actions, often with atypical sensitivity to numbers or patterns. People might repeatedly wash their hands^[14] or clear their throats, repeatedly check that their parked cars have been locked before leaving them, turn lights on and off, keep doors shut or closed at all times, touch objects a certain number of times before exiting a room, or walk in a certain routine way like only stepping on a certain color of tile.

People rely on compulsions as an escape from their obsessive thoughts; however, they are aware that the relief is only temporary, that the intrusive thoughts will soon come back. Some people use compulsions to avoid situations that may trigger their obsessions. Although some people do certain things over and over again, they don't necessarily perform these actions compulsively. For example, bedtime routines, learning a new skill, and religious practices are not compulsions. Whether or not behaviors are compulsions or mere habit depends on the context in which the behaviors are performed. For example, arranging and ordering DVDs or videos for eight hours a day would be expected of one who works in a video store, but would seem abnormal in other situations. Put another way, if the activity helps bring efficiency to one's life, it is probably a habit, if it interferes with one's normal enjoyment of life, it is probably a compulsion. ^[15]

For some people with OCD, these tasks, along with the attendant anxiety and fear, can take hours of each day, making it hard for the person to fulfill their work, family, or social roles. In some cases, these behaviors can also cause adverse physical symptoms: People who obsessively wash their hands with antibacterial soap and hot water (to remove germs) can make their skin red and raw with dermatitis.^[16] To others, these tasks may appear odd and unnecessary. But for the sufferer, such tasks can feel critically important, and must be performed in particular ways. OCD sufferers are aware that their thoughts and behavior are not rational,^[17] but they feel bound to comply with them to fend off feelings of panic or dread.
