Hi Pal, Welcome here.
Feeling tired will happen if you havent got a routine sleeping pattern. I did shift work many years ago and it played havoc on my mind, my thinking, always tired, grumpy etc.
A trip to your GP for his advice and maybe something to get your sleeping pattern in order would be my first point of call. You might also be suffering depression or some other issue. I used to cry a lot, wrote sad poetry and generally was in my own world of high emotion. I was then diagnosed with dysthymia, depression anxiety and bipolar 2. Once the right medication was issued I began my climb back to a stable life.
So a visit to your GP, correct diagnosis, appropriate medication if needed and a proper sleep pattern. You'll feel much better. That's my views. cheers
