Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

• Allergens (dust mites, pet fur, mold, pollen, grass)
• Irritants (smoke, pollution, dust, chemicals)
• Viral infections
• Physical activity, especially outdoors
• Certain medications or chemicals in foods (aspirin, sulfites)

Borderline personality disorder (BPD) is a disorder that causes emotional instability. Once triggered, people with BPD experience more intense feelings that influence how they treat others and themselves. Essentially, people with BPD "hear" amplified emotions at a higher volume and for longer periods of time than those without BPD. Some who have BPD describe "being on the border," often feeling insecure and split between both negative and positive feelings. Mood swings, impulsivity, and insecurity are all hallmark symptoms of borderline personality disorder. No single cause of BPD is known, but it may arise from factors such as:

• Physical brain development: Researchers have found that people with BPD had differences in the frontal cortex, hippocampus, and amygdala - the parts of the brain that control decision making and behavioral and emotional regulation. Brain differences in people with BPD typically occur during childhood development.
• Neglect and abuse: Neglect from one or more caregivers and any form of abuse (both in childhood and adulthood) are factors that may contribute to BPD.
• Genetics: People with a family history of BPD, mental health problems, or addiction problems are more prone to be diagnosed with BPD.

As BPD is rooted in an unstable sense of self and intense personal emotions, symptoms of BPD may vary between patients. Common symptoms of BPD include:

• Rapidly changing moods
• Black and white thinking
• ntense and unstable relationships
• Distorted self-image
• Self-harming behavior
• Dissociation (feeling detached from one's environment, body, and/or thoughts)
• Anger issues
