Narrative:

I was flying a three day trip with a layover. It ended with a red eye leg home. I was only able to sleep 1 hour or so the afternoon before the red eye flight. I was able to operate the flight to my domicile safely. I am on reserve and noticed upon checking my schedule I was placed with a minimum domicile rest and back on reserve that evening. I tried to rest as much as possible that day but had difficulty. I tossed and turned most of the afternoon and probably slept a total of 1 to 1.5 hours. I felt increasingly worse and exhausted. [Shortly after my reserve began]; scheduling called me to notify me that I was being assigned an international 4 day trip with a 3 hour show time that night for a 10 hour flight that night. I told scheduling that I was unable to do the trip because of my horrible state of fatigue I was in. They immediately put me on fatigue for the night and back on reserve early the next morning.
