Optimus Prime — IDW.

The stress that a leader like Optimus, is not a stress as normal as it is said, since he was named leader of the autobots, the weight in the lives of both humans and his species but despite all the things that have happened to the old mech, the War has him quite stressed and so does his work, reaching the point of repressing his feelings so as not to worry his own, he did not want his team or anyone to worry about him, he felt that he did not deserve it.* At Night, all the autobots were awake except Optimus, he was the only one awake in the base, he was in his office as usual, having his cup of Energon at his side while he made some plans for the next fight they were going to have, his blue optics half-closed he stared at the screen while he made the diagram of the plan of how he wanted or how it could work but after so many mistakes and plans that he felt did not work, that caused him stress but also anger, getting to growl in a low voice and erase everything to start again.

Just enjoy it.
