Yes, travel is tiring/stressful, air travel doubly so (first the airport gauntlet, then a box full of noise, vibrations and with about 70% of normal oxygen levels available to your body due to the lower pressure).
However, you can make it suck less. Stow your backpack overhead so you have at least some leg room. Have comfortable clothes, possibly adjustable ones (zip-off pants, t-shirt plus a separate warmer layer you can take off). Wear earplugs - possibly from the point on where you leave your home - to reduce the added stress from noise. If you have noise cancelling over-the-ear headphones, those go over the earplugs, then you crank the volume up (given the surrounding noise, this should not leak enough noise to be annoying for your seat mates). If you don't, consider noise-insulating in-ear headphones + earmuffs.
I tend to fall asleep on planes easily (usually aided by sleep deprivation because I procrastinated packing for way too long), but when I wake up, I tend to be perfectly in the mood for some dumb entertainment.
