I too treat myself like dirt and everyone else as if they sit upon an alter. If someone asks ne a favor, even if ut sends me way out if my way I go ahead and do it because of the guilt I feel if I say no. I know quite what you mean by that low man on the totem pole syndrome because that is how I feel I treat myself . I too don't see myself as important or even deserving. I too believe I'm a bad person and unless I do good deeds only then shall I deserve to eat. I don't know where exactly this came from but partly family influence as well as athletic my whole life. They were all strict and extremely demanding and if not perfect I didn't feel good enough to br rewarded .
