Only you know whether your fooling yourself or not, that is not for others to decide. Sure, people can point it out, but only you can decide whether its true or not. Denial is a natural part of PTSD, have no doubt about that, and that is what you could still be in, denial. All you can do though is not think for others, but instead provide them the information and let them decide things for themselves, let them say things for themselves. If they say something to you that you do not fully understand, then DON'T guess, but ask for clarification. If they are insulting you, then atleast you will know it with clarification over a point, for yourself to then make an informed decision. We cannot guess, we do not know what others think, all we can do is provide the information to them and clarify in order to make our own accurate decisions based on others words or feelings.
