Regarding the "struggle" you depicted: I think the official expression for it is "inner conflict". When different parts (the word "part" means "somebody who is part of the system" and it covers known alters, unknown alters, known fragments, unknown fragments, and everybody and everything in between) want to do different things at the same time, things get chaotic. There are specific aspects of DID therapy who aim at helping everybody take decisions calmly so that everybody inside is happy with the outcome.
Specifically what you describe is what I understand as a struggle between some parts seeking help and communication, and other parts who wants to keep the system safe by not telling anything. It is legitimate to want to keep the system safe. Now the question is: are you trying to keep the system safe from a present danger, or from the memory of a past danger that you fear might happen again in the present?

Time-related triggers can be tied to past events that used to happen at the same time or date. As an example, I still have time triggers at certain dates or at certain times of the day. I do my best to walk around them when possible, and to go through them with the minimum possible distress when needed. There are specific aspect of DID therapy dedicated to managing triggers.
Regarding the pain in your eye, it can be something somatic (a pain from your emotions / Innerworld that is felt in the body) but you are right about getting it checked in case it is physical. Better safe than sorry. Other possibilities include, some orthoptist thingy with the mucles of the eye being strained due to stress or because different alters cause subtle difference in how the muscles are used which can be painful on the long run. If a physician do not find anything, checking with a regular eye doctor and also an eye doctor specialized in eyes muscle could be a good idea. That's what I'm talking about with the muscles:
https://en.wikipedia.org/wiki/Orthoptics An explicit example that I experienced: a very tense and stressed alter (I think it was Zami or at least one part of their sub-system) who would clench the jaws all the time, leading to pains in the jaw joints which can be felt like pain in the ears. The solution to that was: on the one hand wearing kickboxing teeth protection to avoid physical damage on the teeth and jaw, on the other hand working to ease up the stress and undo the triggers of the alter who clenched the jaws.
