Dear @chbartist sir!
Insensitivity in us comes only when there is no good happening in our lives. Irritability is a product of our negative thinking. There are many reasons for irritability in us. Occasionally there are domestic problems. The surrounding environment is contaminated. Due to problems with failures The burden of too many expectations also causes irritation and apart from this our envy nature also causes irritability. It's not that the irritability never ends. Keeping in touch with good people, by adjusting the circumstances, remove the inferiority of mind, avoid the loneliness, etc.
Thank you
