I was picked on for being quiet and clever, which only made me quieter. By end of school I was shy to mute depending on situation, with extreme social anxiety and general lack of any confidence/resilience.
Although I have now put a lot of hard work into becoming a functioning adult with a good job, able to talk to different people, pretty calm and resilient, I still think I have an underlying expectation of rejection that will never go away. I automatically think anybody new I meet is cooler/better/has it more together than me and don't really expect them to like me. I think that comes across to people as a lack of warmth, simply because I'm still quite guarded.
Just curious to hear others' stories - how does it affect you years or decades later?
