If, by the end of the day, nobody has told me that I'm not worthless, or that I am a good person, I get depressed. I feel that I need this so much that I spend much of my time self-deprecating (even when I'm alone) so that somebody will give me their pity. I have a fairly easy life, I don't deserve any pity. There are people much worse off than I who don't need their self-worth to be inflated daily before they cry themselves to sleep. Do I not have legs? Can I not walk on my own? Then why am I always begging for a crutch!?
Have you seen a professional therapist or psychologist? They can be really useful and they may be able to help you with this. I would recommend seeing one of them, if you can.
Having an easy life doesn't equate to happiness unfortunately. Often times when a client has a constant need for help or for pity from others there is a deep-seated need that needs to be ackonwledged. There could well be somehting underneath that perhaps you cannot see. It's a good start to do some free talking. Usually this is done with a professional but you can start on your own. Begin by saying something like "somehting is bothering me" then try to just rattle off and talk without stopping. Foxface
