I think you feel this way because while growing up you had the people around you that were not big on encouragements. That is how I grew up. For my mother was never nothing good enough. So i grew up thinking i need to please everybody and I am not enough what ever I do. It is natural for us to listen to other people in order to survive. Imagine when we were living in caves. If you are not the part of the tribe, then you die hungry! So it is natural that you want other people to listen to you and appreciate you. But the problem is that your young experiences where too negative and bloke yours spirit. But there is a way out! You can decide that you want to more, and you will stop listening to your story you keep on playing in your head! And - be easy on yourself! Be your own best friend. Would you treat a friend as you are treating yourself?
