it is a state of mind, often related to low self-esteem and being disconnected from your emotional processes.
you can work at it, learn to love yourself, value yourself, notice when you succeed, accept that you never failed, just not YET found the right way.
when did you last tell your heart "i love you"?
respect, from robbie
no love in life
Attitude is most of it. Living in a large city and being afraid to make friends with strangers could be another. Some people are desperate to be with others, cannot entertain themselves if they are alone in their home. That is a marker for a personality disorder.....I can always find something to read, to clean, to cook, to make or organize around my home.... if I am snowed in for a half-week, I'll find something to keep me busy so I won't feel alone.
State of mind, way we think and behave.
Not being a sociopath.
