Related to autism or not?

15F unofficially diagnosed with high functioning asd

Soooo when I get frustrated/angry I tend to feel like biting stuff, or throwing stuff, or hitting stuff. Last time I felt like that I bit my own arm and ended up bruising it….

It’s different from my meltdowns (where I usually feel like I’m completely losing control), I can calm faster but yeah, I find that extremely embarrassing to be honest, I feel like a spoiled kid that is overreacting or something
