I'm going to take a chance and tell you how I feel...It's taking a chance to post your true feelings on the internet but here goes... for what it's worth...Sometime do I not only feel that others have no value but that the only value they have is negative...! In otherwords worse than no value... No value AND Less!
But that's just a feeling... These feelings come and go... People seem to me to be getting colder and nastier... And it seems that when you are needing people like we are, the ones that pick up on it are the nasty ones... Regular people are out there trying to run their lives...trying to take care of families... etc... They are not necessarily paying attention to you because they are busily taking care of their lives... BUT the nasty ones are out ther looking for trouble...
So problem may be that you are receiving feedback from the wrong people... And yes, they can have a strong impact... But maybe you can think of others like Dr. John or Zora... and maybe they have a little value... right?
Seems like you are just down on yourself. Worring too much because of it. You could be right...
