Eating makes you tired, how are other activities? does your eys drool. how is your muscle status, has any body in your family history of eye drooling
or muscle wasting disease, you said it progresses with the day.
if there is some positive family history of myesthenia or multiple sclerosis
or lambort eaton syndrome or any other myelopathy
than you should have a thorough check up. if not then you are safe and out of woods.
all you need is sone reassurance and a psychiatric consult with therapies to reassure you. Most of the time it is anxiety
which makes worse of the little situation.
so in nut shell you are too young to be involved in some serious trouble. cheers:)
