Re: can anyone please tell why im so tired?
If that extreme it's unlikely to be just a problem with sleep.. well, I'm no doctor, but you sound like you have the same problem as me, though I am in my early 20s and do get enough sleep.
I don't wake up at night, but I do wake easily. I can easily sleep 7-8 hours straight, but any unfamiliar sound will wake me up. But that rarely happens, and I did take a sleep test and I'm fine in that regard.
You can read my post "why the hell am I tired?" which is currently on the front page of this board..
I'm really not sure what to tell you, but I do share your grief. I've been extremely tired for the last 10 years, and it has resulted in me failing my classes over and over (I literally would repeat the exact same schedule every semester), not being able to work (acquired a $20K debt), and pretty much spoiling every relationship I've had with family and friends, and nowadays my wife.
Things are better now. I have a great job and if I work hard, I can pay off my $20K debt before the summer ends, but I can't get myself to do anything. I feel indifferent and annoyed, and it takes me hours to complete a one hour task, because I can't focus. I also yawn 24/7 (and did so before the meds).
Good luck! Please share what you find out
