NC.
From when I was tiny, my parents told me I was fat. I wasn't. They had different kinds of health anxiety around my brother and sister, which kind of explains it, but I resent it hugely. It surprises me so much when I see pictures of myself at any age under ten (when I started to get fat for real), because there's such a difference between how I looked in my mind and how I really was.
Then I went to a vile boarding school for seven years. I was bullied every day and I had no ability or tools to deal with it. I was totally innocent and unprepared. I was told on the regular that I was fat, ugly, retarded, needed a face transplant, nobody would ever love me or fuck me, that I smelled, that my clothes were shit (tbf true, but still). There was nowhere safe to be, and no safe way to be me. I retreated into books, only to have a teacher tell me that I was too quiet and she wanted to see me joining in more. I'm sure she meant well, but I went to the toilets and cried and cried. She took away the last thing I had left that I enjoyed and let me escape from the horrors elsewhere. She took that and told me it wasn't good enough. I CAN'T TRY ANY FUCKING HARDER, BITCH.
It left me with complex PTSD, I'm still working through it thirty years later. Even though I'm now happily married with kids and have been objectively very successful in my career, I still feel it's all a mistake and it'll be snatched away from me at any point. I have rejection sensitive dysphoria. I really get the others on this thread who've said they feel unsafe to make a mistake or to ask for anything for themselves, and that they feel responsible for the happiness of everyone around them. That's all me. It is fucking annoying because I expend so much pointless energy just in getting through the day without collapsing. If I didn't have to do this I'd have a bastard Nobel Prize by now.
I've had a fuckton of therapy and I'm still a pile of neuroses loosely held together with...fuck knows what, actually, since I gave up drinking. Glad I did, obviously, as it nearly killed me and I have no idea why DH didn't leave me, with all that I put him through.
