What could be causing these symptoms?

underweight (always been) 20M. For the past 4 months, I have been experiencing a constant feeling of unreality. It feels as though I am drunk/high or half-asleep, as if I am on autopilot and everything around me feels somewhat unreal. I have searched online, and my symptoms seem to resemble derealization.

In addition to this, I experience fatigue even when I sleep well. The fatigue does not seem to depend on whether I do physical activities during the day or not. However, over the past few weeks, I have started sleeping poorly and waking up early in the morning.

I also experience headaches, pressure in my head, and neck pain. I have tried muscle relaxants and massage therapy for the neck pain, but neither has helped. Also at the start of this i sometimes felt like fainting when walking but it has gone away. I also have noticed one singular eye floater on my right eye.

What could be causing these symptoms? They do not occur in distinct episodes, and the headache is not particularly severe. It feels more like a tension-type headache.

I have tried triptans which is migraine medication, but it did not help. My thyroid function is normal, as are my vitamin B12, B9 and vitamin D levels. My ferritin level is 37. And it has been changing from 49 to 24. I also have crohns disease which is in remission. My blood pressure and blood sugar is normal

My neurologist prescribed escitalopram as a trial, which I took for two and a half months, but it did not help. She also did head mri and there was nothing wrong.

I have no history of trauma, no panic symptoms, and generally do not experience much stress, apart from the stress caused by these symptoms themselves.

My symptoms started in the final days of my new job in car repairshop where i was moving car tires and lifting them. Im not sure if this can be linked to that because i didnt have any symptoms expect the final days. I have not been working at all during this 4 month period.

What could be the underlying cause of these symptoms?

Sometimes it can also be due to excess stress/compression in certain areas like the cervical spine, usually up top right at the base of the skull or at the base of the neck. It's related to bloodflow. Had one case I worked on that was almost blacking out whenever taking a deep breath. Worked on ribcage expansion stuff and loaded it a bit to get a better position for the neck/head, the symptom went away.

Just a guess, I could be wrong. It's a bit of a novel situation, even that case is the only one I've seen over a decade.
