i wouldn't say mine were necessarily low in IQ but more that they had different ways of coping, different personality traits than me, and overall were able to deny things better when things happened and take care of themselves compared to me who was the youngest and no one really there to protect me like i needed. i also was very quiet, shy, anxious, afraid, etc. where they were the opposite, loud, opinionated, able to fight back/stand up for themselves, etc. so, i grew up feeling different and 'wrong' because i was not like them...but i wouldn't change how i am to be like them because i feel like i am a better person in some ways...i care about others and am just..not like them...
