>>41607420seize control of your mind, menheraposter. you said it yourself, you have trauma relating to your past that makes you feel bad about yourself. don't let it project itself onto your current day social relationships. other people don't deserve to be seen as extensions of your shitty parents or what have you who didn't value you, or to be mistrusted when they're earnestly trying to communicate that they like you. don't let your insecurities turn you into the kind of person who would accuse everyone around you of lying, internally or otherwise.
most important thing my therapist ever told me was "it sounds like you assume everyone you meet is gonna treat you the same way your brother does."
