All of your symptoms I have endured, excepting two, are for me Just Migraine. Very possible something more is going on, Of Course!! You mention light headed ness on standing w a kind of black out sensation- that sounds exactly like what I experienced due to low b.p. the lack of motivation, concentration, sounds like mild depression which is comorbid w depression. Really just wanted to ask you to check your bp as soon as possible! It's an easy free or cheap teats, and a potentially life threatening condition. It's so frustrating when you have tons of weird symptoms, it's possible you could have different causes, or it could definitely just be classic migraine w aura- good luck, best wishes
Hi...I can only suggest u go to ur Dr get tested, blood panels, and a brain and cervical spine MRI.....
Low levels of vitamins and minerals can produce some of the symptoms u mentioned....and they can also be a result of a neuro issue...so do get the MRI;s done as well and see what ur Dr can find and post an update.
Good luck
