Merope,

Read the vitamins sticky.

B-12, and folic acid are helpful in rebuilding the myelin sheath that covers nerve fibers. Much of concussion damage is due to strains and breaks in the myelin sheath. The myelin sheath heals very slowly.

When the myelin sheath is damaged, nerve signals can short circuit and leak out between neighboring nerve fibers.

Star burst and streaking can be the optic nerve fibers short circuiting or other issues. Light tails as the eye looks away from a bright light can be the nerve cell not releasing the image to be replaced with a new image. Everybody has it so some extent based on the brightness of the object.

The ghosting can be a serotonin reuptake issue. The neuron does not release the neurotransmitter fully across the synapse and reuptakes some of that signal to be presented a second time.

Your anxieties and OCD like thoughts are common to this neurotransmitter reuptake issue. I take 5-HTP and L-Theanine to help moderate this. It works better that high doses of an SSRI drug.

These issues are magnified in you because you pay attention to them. Most of them have always been happening to a lesser extent. Now, your attention to them is in overdrive and you struggle to ignore them. CBT, Cognitive Behavioral Therapy, can help you redirect your attention. You can also learn your own thought responses to them.

I don't make these comments from a purely 'these are the facts' sense with no understanding of how they impact a person. I live with these issues and have lived with some of them for decades. I know I can choose to pay attention or I can choose to ignore them. I recognize they happened or are continually happening and stop trying to explain/understand them and choose to move on with life.

I do what I can with good sleep and healthy eating and supplements and accept the result as the best I can achieve and move on.

Maybe this analogy will help.
If all you have is an old car that uses oil and gets lousy gas mileage but otherwise runs, if you keep it full of oil and gas, you can still get to your destination. In fact, your destination does not care how you got there in most cases.
