A long battle with
insomnia is very distressing. It is most commonly known to be secondary to other stressful factors in life. As you have mentioned, you sound like someone who tends to get tensed and feels stressed out easily, which often means, having high level of
adrenaline in your body. An anxious persona with a non-refreshing sleep strains the body causing compensatory rise in the adrenaline levels and hence the rapid pulse.
The headache, watery eyes and
fatigue are all signs of lack of rest to the body and mind.
In order to be able to make a diagnosis and suggest treatment options, I would want to know a few more things about your problem:
1. How is your mood most of the time, in most days of the week?
2. Do you have any complaints like getting tired easily, losing interest in your work or your routine, not eating properly, feeling worthless or crying spells?
3. Have you tried medication for this problem? If yes, which one and for how long?
4. Do you have any dreams? Can you remember them?
