Thinking about getting a neurological assessment

I’ve been thinking of getting a neurological assessment because I have a lot of sensory issues/sensitivities such as 

• Not properly processing verbal sentences, stories, feedback, or instructions. ( often times I don’t hear the words, just that they are words and have to repeat  it back verbally to myself)
  
• Easily overstimulated by noise, disorganization, sterile lighting, textures, and tastes.
• Poor spatial awareness ( needing my hands to tell left from right, not being able to properly estimate distances, cant really use a ruler properly, and hard time following directions to a location)
• Aphantasia 

I’ve talked to my mom about it and she has told me the name of the process I would have to go through and it seems really overwhelming. She said first I have to talk to my school counselor. She knows how the process works because my brother has been evaluated the same way I want to be.

I just wanted to know if anyone has some tips or comments about this so I know how to approach it.
