I am other hungry and other tired lately even when I know I've eat and slept adequate.?
Answers: It could be various things.
Stress, as someone said. Especially the bit about getting foolish. Try relaxation therapy - buy a proper, medically vet relaxation tape - not of late new agey music or whale sounds or something - but progressive, muscle relaxation.
You might be anaemic. Find some one full of vigour, and stand next to them within front of a mirror. Gently pull down your lower eyelids and compare the colour. If you are much paler than him/her, you might be anaemic.
You might only just be due a holiday.
Or it might be thyroid or something more serious - but try the others first.
Diabetes?
