Feeling sleepy, EXTREMELY fatigued & Stressed even after I have good sleep. also during work. What can be the cause?

We can't tell you the cause. Diagnosis cannot be given on the Internet. See your doctor to sort it out.

A few minutes before you asked this, you added on to an old post of yours that you are fine and doing great. Which is it?
There's a good chance that the stresses of your failed relationships, your childhood, your family life now - are all hitting you at once. Did you solve the problem of being gay in a culture that doesn't accept it?

Most importantly, did you ever have sex with the man who was having sex for money? Could you have HIV or AIDS?
