The thought of I'm tired will definitely make you tired. Otherwise, if 2-3 people whom you meet one after one start asking you why are you looking tired, will also make you tired. I think everything is mind.

The actual process of feeling tired?
When your brain decides it-or the body--needs to rest, it triggers the release of "sleep poisons" such as melatonin, serotonin and tryptophan.
You get the same tryptophan (L-tryptophan, I think) in turkeys, and this is why you feel sleepy at thanksgiving or Christmas.
You know that characteristic smell of a bedroom, especially whn people are actually sleeping in it? That's melatonin, and if you stay long enough, you find yourself yawning.
The US military has worked with pharmoceutical companies to develop melatonin blockers, such as Provigil, whihc allow people to stay awake for up to five days.
Look up melatonin at wikipedia.

our busy everyday lives without taking time for
God and ourselves the way we should. Vitamin difiecency and it sometimes leads to depression, which will make us tired. Our husbands not talking to us about things that matter. Just life.

I think that guy said it all, but make sure when u sleep there is no excess noise, ie tv, radio, fans ticking clocks, and anything u can do to reduce it - try and take care of it. Our brains don't get proper sleep when there's noise, even tho your body is asleep, your brain is still activated due to noise.
Sweet dreams sweetie :)
