Possible ASD Symptoms - Seeking Diagnosis

I really relate to a lot of asd symptoms. I will be seeking a professional diagnosis. I recently realized I might have ASD when my husband said they suspect they're brother has it. I relate so much to how his brain works. I can get overstimulated with noises, or too many people. textures of food is extremely important to how i enjoy or able to eat it. i have i really hard time processing auditory information unless Im extremely interested in what's making noise or what's being said. like my husband explains a mtg card; i just cant process it, even a simple one unless i know it already. i have to have it explained one step at time and slowly. or i can just look at it. i feel that my brain obsorbs visual information like a dry sponge. but for some reason i can't put my detailed observations in a physical order. i tell people that im directionally blind. like i got lost in a McDonald's the first few days I worked there. i had to consciously find physical markers of exits. i often can't find my way back from the bathroom at restaurants, unless i put a lot of mental energy or i can see my table right as i leave the bathroom. i just have to put a lot of mental energy to make routes and lots of repetitions to make it stick. it was awful working as a janitor for 15+ buildings. i feel safest and happiest having rigid routines because making them is very mentally expensive amd having them lets me know what to expect. i used to have a really bad stutter that got worse with feeling strong emotions. it felt like the words weren't coming to my mouth or sometimes my brain. Sometimes i become mute for a multitude of reasons. like nausea, age regression, or my brain becomes so overstimulated it shuts down the speech part of the brain. i use hand signals as it makes a lot more sense in my brain i have an alter that deals with complex socialization. but she is so energy expensive. it feels like my brain is an old computer trying to run a new pc game with patches to run it. and socializing overheats it. i also obsess over the same episode, food, video over and over again. but eventually i lose interest and obsess over something new. but that process often takes months. Does any of this sound like asd? I know it has a lot of different symptoms that could be something completely different and require a professional who specializes into. but im curious what other people think
