it is in fact absolute youve had it since birth, and its actually a heredity thing! so someone in your family probably has it too, even if they dont know, or grandparents. asd is a vast spectrum so you could have different symptoms, experiences than someone else might have. one thing is not understanding certain social cues, or vague instructions, for example, put the chicken in the oven, and doing only that, when they expect you to dress it and turn the oven on and cook it. another example of not understanding social cues is thinking someone is being friendly when theyre bullying you unless theyre physical about it, which even then sometimes doesnt work either, or thinking your not being rude but people will say you are because of missing cues they think are important. there is sensitivity to, alot, textures, flavors, smells, lights, sounds, which id say its more of, instead of our brain filtering excess stimulation, which is what the neurotypical brain is wired to automatically doing, ours, doesnt, so it can feel like its louder, because it is for having asd, so i hear, smell, see, feel things with no filter, which causes easy overstimulation, though its worse for some than others, you can also look at the dsm-5 symptoms, it might help, there is a website you can check, i also recommended avoiding help if you can from places that rep autism with a puzzle piece, they treat people with asd like they need to be fixed or cured

yeah, i kept thinking to myself while figuring it out that i would know that its obvious, but its not obvious when you dont know about it at all and rely on what i was taught by, very abliest people and shows with bad rep. although it feels obvious when you know about the symptoms and how it affects you while thinking about the past lol. you can get either normal earplugs, but there are some earbuds for sound that they have different ones for different decibels by Loop. another thing is alot of people usually have textures they consider bad textures, because instead of feeling soft velvet or paper towels it feels like being scratched or hurt by all the individual bits instead of it being soft blending together, it can be anything else that disgusts you to touch hobestly, for some its chalk or Styrofoam even, theres alot

Okay, but you are born with Autism so if you were diagnosed I would tell your doctor that they need to talk to you about things basic like being born with it and important symptoms that can mess with your life, such as the ones you are mentioning, instead of just tossing you to the side without information.
