No Diagnosis, Can't stop thinking about it

This is my second time writing this thread because I didn't like the level of detail I had gone into before. I am just going to keep it simple.

I started noticing patterns in my day to day life that are, according to people I speak to, not common.

Examples:

I struggle with using data properly when creating spreasheets at work. A lot of the time, this boils down to placnig things in the wrong location because I have trouble tracking with my eyes what rows/columns to use. Counting and place marking seems to be the issues.

I skip over large swatchs of information accidentally.In school, this was a big problem cuz I would miss entire questions this way even when re-reading after completion.

I often say or write the wrong words, especially in casual conversation. This is especially bad with names (I can say the wrong peron's name 4 or 5 times in a row sometimes), but also happens with other words, like using Quest instead of question, or Mic instead of mouse, word instead of work. Sometimes even as outrageous as boat instead of car.

As I became more aware of these nuances, I asked my mother (parents are split) about if I was ever tested. I was informed I was not. When I asked why, she told me that my father refused to get me tested because it didn't really matter and he didn't want people looking at me differently or for me to not succeed. Despite this, they did have my brother tested and he was positive for ADD. I think my father may have had this stance due to my acceptance into gifted and talented for high IQ (I had a very poor reading comprehension until 2nd grade but I guess that didn't matter).

Of course, this bothers me a lot. As a parent of 2, I am a big fan of testing even when not medically necessary just to ensure that everything is okay for my kids. While I was able to overcome difficulty reading, I still struggle daily with the above topics. I function well and don't feel very limited, but it i still frustrating to me to know I deal with these problems

I also read that common symptoms include touch sensitivity, and while I don't have much to compare in regards to wether or not I deal with this, I definitely feel as tho my skin is more sensitive than those I know. Touch is my favorite sense, and sometimes touch can be overwhelming. I am inconsistent/touchy when it comes to people touching me. I feel like I am always itchy too which leads me to consistent irritation.

What's the best way to go about resolving this issue for me? Is testing really necessary if I feel like I function well? What good would testing do to me? Would it calm my mind or would I have more questions than answers? What type of costs/services are associated with testing? Who else has had similar experiences?
