Is this a form of dissasociating?

So recently more and more I've just been wanting to close my eyes because I find comfort in it.

I've recently had a decline in vision in one of my eyes, a blind spot that my optometrist could not explain and she said there was nothing physically wrong with my eye.

I've also looked up other things trying to find some kind of explanation about why I feel this way. I've came across something called Sensory Processing disorder, I often get extremely overwhelmed by sensory when I leave my home or a controlled environment to where I can experience a wide range of emotions which is sometimes embarrassing. For instance, If something is too loud I can become fearful or angry, if something is moving too fast I can become fearful or anxious. If something is too bright, like the sun or lights inside stores it can be overwhelming and make me anxious and if its a combination of many things I can end up crying, then feel sad after.

I've found a comfort in not having any visual stimulation if it's outside of my familiar environment. Usually if I do go out and deal with a lot of sensory even for just an hour I am completely drained for weeks, sometimes even months. But, recently I am unable to handle certain situations completely because of overloading process.

I've dealt with a lot of things in my life that haven't been resolved and I don't have much of a support system. I'm curious if anyone has had a similar thought or if this could be considered disassociating.

Connect a few ideas feelings could be associative. Sensory processing is just a symptom, a weeding out if the doctor is thorough enough, mainly just ask them and make sure to take notes, then you will find out what exactly is the problem.

first I want to say that here in my location we have two different words that get confused and mixed up with each other.

Dissassociation (A between two S's) means to purposely stop doing something and is not a disorder because its normal for people to change their minds, stop doing activities and so forth... example last night I stopped reading my book and went to bed and closed my eyes to rest. this is an example of Dissassociation (willfully and on purpose stop doing something, willfully and purposely not engaging in life outside my self,

Dissociation (no A between two S's) here in my location now defined as a normal reaction to a trigger. like if someone said something to you that you did not like your body would automatically feel angry. with dissociation something happens that causes someone to feel numb, lack of emotions, like they cant mentally feel anything, kind of spacy foggy no thoughts in the mind kind of mental feelings. theres a physical brain response called Flight or fight that goes with this. someone experiences something so triggering their their brains normal flight or fight response to that trigger kicks in causing that person to feel numb, spaced out and disconnected.

related to your own problems my suggestion is contact your treatment providers, they will tell you whether this is an eye problem or any other number of problems in you including diagnosing whether this is a dissociative disorder in you.
