Emotional instability is the prolonged emotional reaction to a particular emotional experience even after it is over. It involves reinitiating the certain response frequently. It is said to be the heightened sensitivity for a longer duration to disappointment, failure, separation or rejection. Emotional instability is not an actual disease as those who go through it are capable of loving and experiencing joy. It is their reactions at certain uncomfortable situations that are highly passionate. An emotionally unstable person experiences limitless shame even in cases of slight embarrassment, immense stress in cases of minor nervousness, anger in place of slight irritation and extreme grief instead of momentary sadness.
