When you say something like "people just dislike me", or something like that I feel like saying that "people" is too general. There may be some people that dislike you; or maybe you have some traits that are less valued or socially awkward within the group (or society you move in) But when we say "people" is too much and leaves things out of our control (sorry my writing is obscure, hope you understand). I think you are right when you say that those thoughts are part of a combo that comes from childhood. It is important to be aware of it as it is not rational and not true and can be damaging your life. To me each time this kind of thoughts come to my mlnd, I accept them as part of my past but I tell myself they are not right
