Narrative:

I was working uim-lo; a low altitude; east; departure sector east of dfw approach control. I was working by myself with no d-side or handoff. I was feeding 2 high altitude sectors; txk-hi had a radar and a d-side controller; slr-hi had only an r-side. Before I worked the radar I worked the d-side on uim; before that a computer based instruction test; before that another 'cbi.' I had been moved from position to position with no breaks just to make sure my time 'had been productive.' air carrier Y had departed dfw and was flying out the 084 degree radial on its assigned departure route. Air carrier X had departed dallas love and was flying out the 094 degree radial on its assigned departure route. Air carrier Y always flies slow; air carrier X always fly fast; except when I'm not paying strict attention. I cleared air carrier X direct tekbe; a fix on the departure route; to short cut him a bit. I thought the air carrier X would out perform the air carrier Y. Air carrier X didn't. The turn put air carrier X and air carrier Y into confliction. I screwed up. At the same time the mental anguish that has been surrounding me because of all of the imposed work rules has really been causing me problems. I was tired due to lack of sleep; hungry; because I kept getting moved around from task to task; position to position; the cafeteria closed and I couldn't get food. I'm jumpy and full of self doubt because management is continuously hammering on all of us. I have no safety net and don't want to be a controller anymore.
