Narrative:

The issue arose in the timeframe preceding the trip. I was on reserve only mar/xx; but contacted approximately XA00 by the crew desk to cancel my day off and assign an XJ35 departure on mar/xa. I indicated 'fatigue' and asked about other alternatives and legalities. At the time of the call; I would only have a maximum of 5 hours to sleep under perfect conditions. The crew desk denied my 'fatigue' statement and indicated I had enough time to sleep preceding the assignment. I spoke with the duty manager; who indicated the trip was legal and I must fly. After packing and the stress of canceling major plans; I could only manage 3 hours of sleep. Upon departure; I missed radio calls; routine items; and fought to stay awake. I was not an asset to the captain and unfit to fly. My sleep was also compromised by the need to pack and other items not anticipated when scheduled for 1 day of reserve and subsequently assigned a multi-day trip. Despite my indication of stating fatigue; the crew desk compelled me to fly in condition where I clearly felt unfit for duty. Although there wasn't a specific SOP or far violation; I acted in contrast to the FARS; which require I report rested and fit for duty.
