Bipolar people are generally emotional and impulsive. At times, their sudden mood swings create problems for them and others who are related to them like family, friends, and colleagues. This has nothing to do with morality and conduct. If a normal person screams at his colleague, he might be mad at him regarding work related stuff which might be a genuine reason but if a bipolar start yelling and over react in the similar situation, it is more likely to understood and perceived as bipolar mood shift. It might be true that the mistake of colleague is not that serious and he over reacted and created fuss in office because he is a bipolar. But in this case too, the seriousness of mistake should not be judged on the basis of disease.
This was just an example. More such cases happen in our families on daily basis. Anger, sorrow, frustration, excitement, these all are common moods that are experienced by every ‘normal’ and ‘abnormal’ person on this planet. In fact this happens with animals too. But when a bipolar is having a specific mood due to some particular incidence or situation, it is perceived by family as medication disturbance and they force you to plan immediate visit to doctor.
In the same way, Bipolar doesn’t afford to be ‘nice’ at all. When you care about your family, give attention to friends, organize your wardrobe, help mom in kitchen, discuss politics with dad, visit grand ma on weekend, dress up nicely, and feel good about your life, this would ring alarming bells to your family and those you have come out to. Something must have gone wrong with the medication that’s why s/he is so happy and excited. Let’s visit doctor before the condition becomes psychotic.
