Hi, welcome to the forum, you are experiencing long-term sleep disorder - insomnia. They may also be associated with sleep disorders (eg, sleep apnea, periodic limb movements), medical conditions that cause pain, psychiatric diseases (eg, anxiety, depression), or the use or withdrawal of alcohol, nicotine, or other substances. This can be associated with headache but other causes like exertional headache, migraine should be ruled out.
The investigations which will help to diagnose the type and cause for insomnia are Polysomnography, Multiple sleep latency test and Actigraphy .
The therapy for this condition includes retaining of normal circadian rhythm by non-pharmacological therapy which includes; Photo therapy, maintenance of sleep hygiene. You need to go for morning exercises and work out which will make you fresh and active all day and tiredness at the end of day will help you to induce sleep naturally.
Pharmacological therapy includes short course of appropriate sedatives and Hypnotics against prescription. Non-benzodiazepines are effective in delayed onset sleep disorder and help to initiate the sleep. Along with this you also need behavioral therapy.
I suggest you to consult physician. Take car and regards.
All of these symptoms indicate on blood pressure in your brain that change your body clock.
