Very true. I do believe that, while an individual is the only one who can look in to themselves and feel who they are, many don't know how to identify their own feelings, or simply ignore them. Many don't see these feelings, until you've identified them. I've met many women, especially mothers, who are self-sacrificing individuals, who always put others in front of themselves. Many simply see these people as saints, looking for nothing in return. Don't get me wrong, I appreciate these people, as I understand their turmoil, and really do appreciate their help. I find, most of the time, they behave this way because they have made it their mission to help others, as it gives them purpose. When they are left to their own devices, and have no longer have responsibilities for others, they are lost, and feel redundant. As a result, many go out of their way, searching for other people to help, as they don't know how to look out for their own needs, and so are prone to being neglected, abused, or taken for granted. When I come across such individuals, I sometimes attempt to encourage them to do things for themselves, as many of them are actually surprised at the suggestion, and never think to do so, unless others first suggest it.
I've read several of your posts on this site, and understand why you feel the way you do. You do not feel the need to hide your opinions, and approach conversations with a blunt tone. It's not unnatural for someone to do so when they have been exposed to much abuse. Many people don't understand, and may tell you that's not the proper way to behave, though they don't understand that people will mimic each other, and if they are polite and kind, it's usually because they were raised in such a manner. In saying that, this is my advice. While many see me as a rather cheery person, I myself choose to display a persona more accepting to society. Like you, I once thought there was no point in nice behaviours, as I too felt I was respected more when I was less pleasant, but learned fast that this can leave you lonely, and learned to balance both. I strive to have a personality that is socially acceptable most of the time, while also standing up to those who choose to bring me down. It's hard work, don't get me wrong, but I personally have found it to be a rather rewarding challenge.
