You’re still not getting it, though. Read @Pinktartanjamjar ’s good post about therapy helping her understand the roots of her own people-pleasing again.
You need to let go of the ‘too nice for your own good’ idea, and see it as the character flaw that it is. Obviously, you didn’t pull this out of the air — you learned from somewhere, probably in childhood, that the way to make people like you was to be compliant and eternally helpful. That’s certainly what I learned. It’s an ingrained pattern of behaviour that’s difficult to shift, like nail-biting or comfort eating.
The problem is that it doesn’t work, it doesn’t make you happy, and you spend your life trotting around servicing other people’s needs while at some level, consciously or unconsciously, resenting the fact that your needs aren’t being met.
The typical pattern that ends up being described on here is that the secretly resentful people-pleaser finally cracks, and then comes on Mn to recount bitterly that their ‘friends’ never got in touch again after they ceased to be useful, and continues the narrative of ‘other people are CFs and users and I’m too nice for my own good’. When in fact they need to take some responsibility for creating the situation.
You have to have allowed yourself to be exploited. You had to have been trying to elicit a certain kind of response from others when you were taking annual leave to babysit your friend’s children, or taking daily hourlong phone calls from a hypochondriac windbag who never asks about you or invites you to her parties, because you’re not fun, you’re just a personality-free listening ear.
Those were choices you made. Own them. Think about why you made them. What did you think you were getting in exchange? Think about who or what taught you liking could only be bought by compliance and usefulness.
