I stimmed as a kid and felt shame about it. My mum was emotionally abusive so I never wanted to be in her firing line and I tried to be fairly invisable as a kid, but, being as Autie as I am I have never been able to help stimming so it's taken various forms. I chewed non food things as a kid (kind of gross I know), I've always been a thigh slapper, and a expressive move-aroundy person; vocal stims are also a big thing with me, I used to whistle as a teen, and singing was a constant for many many years. I'm a toe tapper, a finger drummer, a stroke-myself-to-soothe myselfer, a read-to-hide-from-the worlder, a weird sound maker, and to answer the question ~ YES, I no longer shame myself for my weird autie behaviours. Sometime I am stressed and overwhelmed and I kind of remember, "Oh stimming, it's soooo comforting (Oh course, I'm already doing it, automatically), it's just that I really embrace it and get way more comfort out of it and I'm MINDFULLY stimming and it's SO MUCH BETTER and more comforting!
