By value, do you mean how much other people need you or how much you help others?
If that is what you are asking, that is one of my biggest issues with life......and yes, I believe that I am of value if people need me to do things for them.
If I can't, then no one ever bothers with me, pushes me aside and generally ignores me - hence I feel abandoned and rejected.
If I do a good job at work and receive praise, then I feel like I have value as well.
It's not a good way to view yourself.
