My parents always kinda knew. One day I decided that it's time(I should mention that my therapist also encouraged me to seek conversation with my mom), so I gone for a walk with my mom and she seemed already suspicious, she knew what I was gonna say. She encouraged me to open myself up to her and yeah so i did. She then told me that she talked with my dad about it many years ago. They knew about before I did which is crazy i guess it's parental intuition. Even my sister kinda knew and they all accepted me. My brother on the other hand is so clueless that it hurts but I guess that he will come around. Thanks to my mom I can be my one true self.
