This was somehow the peak of a general sad "hype" that I notice more often lately: People are doing wrong, get advised or others try to help but those people are heavily resistant to insight and refuse any chance to improve (a situation or themselves as a whole).
Is it so hard to even just review an advice kindly given? - In most cases I experience, people are building up walls and raise their weapons for self defence in an instant without even thinking 30 seconds, if the other person's thought could be worth appliance/implementation.
In communication science they tell you that in written form a lot of elements get lost and it is always better to communicate face-to-face. I say, face-to-face is not always the best way because when people are alone, hidden behind their laptops or in their beds, they are more likely to spend a minute on self reflection or review their thoughts of the day.
When you get critics, think of the chance to improve! Others who have given up on you, won't bother to correct you, they just stopped to cope with you. Those who criticize you, are still interested in you and want to socialize with you!
