As hard as it is, being sensitive to others means that one is not sensitive enough to one's self. If you don't have much self esteem or know yourself well enough, it's too easy to care what others are saying and doing instead of concentrating on what you want and are doing.
Everyone has their "goals", what they'd like and are working on. If you are working on finding a job, (as an example) and have decided to go to the library from 9:00 a.m. to Noon everyday and research/work on getting interviews, etc. your friends, loves, parents, teachers, anyone else saying, "Gee, you are lazy only working 4 hours instead of all day. . ." should not bother you because you are doing your thing, for your life, your way!
However, if what someone else says does impact how you feel (strangers or what "others" online/on the TV, etc. are saying/doing shouldn't impact you much at all, ever), it is a good idea to look at what they SAY, not how you feel! You do have to do some reality checking. If you parents say they think you're lazy and you are living at home, on their money, they may have a valid reason for saying what they say and you have to appraise it realistically. Looking for a job an hour a day and "hanging out" for the other 7+ when you should be "working" is not appropriate if you are living off someone else.
But, the short answer

is that you should look at what is SAID, rather than how you feel. Concentrating on how hurt you are doesn't help at all, looking at the situation and checking to see if it is "your" problem or the other person's can help a lot. What other people say is their opinion and is not about "you" primarily but about them and how they see you. How THEY see you is not how YOU are.
