Sector 39 was working Aircraft Y. Aircraft Y was deviating in to my airspace due to weather on its filed route. Aircraft X was a departure and I immediately noticed that Aircraft X and Aircraft Y would be a factor for each other so I took action to turn the Aircraft X to a parallel heading (heading 240) and gave Aircraft X a climb clearance to FL 280.Aircraft Y was climbing somewhat slowly out of FL250. I evaluated the vector and decided that the turn was not sufficient provide separation so I again instructed Aircraft X to turn to heading 230. At some point; I made a point out to sector 42 to climb the Aircraft X to FL 360. Instead of issuing the Aircraft X a clearance to climb to FL360; I issued the Aircraft X an instruction to fly a 360 heading. I believe that I simply made the mistake of moving too fast and making a simple error that I did not catch. The loss of separation then occurred.I believe fatigue was a main factor. I am a reservist in the [military] and currently am on a stretch of consecutive work days in a row between the two jobs. The FAA schedules me [multiple] days a week; and the [military] also schedules me to work in that same period of time. My schedule over the next [few] days only allows for [a few] days off between the two jobs. I also believe that stress caused by uncertainty about my military leave during the previous week was a contributing factor. I had military leave approved; and someone in management made an error and cancelled it erroneously. I had to scramble to make sure that my absences were excused. Pay attention to what you say. Slow down. I feel that had I slowed down my pace that I would never have made such an unusual error.
ZNY Developmental Controller issued a heading of 360 degrees to Aircraft X. Controller meant to climb Aircraft X to FL 360. The 360 degree heading put Aircraft X into conflict with Aircraft Y. Aircraft Y was deviating for weather on a different controller's frequency.
