You forget who you are

Your personality becomes defunct
you spend so much time thinking about others that you forget about yourself. If your neighbour's canary has died, you don't have to stay up all night consoling the poor old dear if you've got a piece of work to complete for the next day, so don't do it! Other people live their own lives but you don't seem able to: you're like the sacrificial lamb. 

Extreme consequences
Therapists warn that over-generosity and kindness towards others can result in a complete absence of self-worth. Some people who suffer from this problem can even end up borrowing sums of money they can't pay back just to please others. They'll take anything from a partner and are prepared to go to any lengths to please him (think masochism!). If this is the case, action is required, and immediately!
