exhausted, tire, weary
疲 centers on the state of being drained of energy: exhausted, tired, or weary from effort or strain.
疲 combines 疒 (sickness) with 皮, which likely contributes the sound and may suggest the idea of the body's outer covering being worn down. The exact historical development is uncertain.
The sickness enclosure 疒 wraps around 皮 (skin). Picture an illness that makes your skin feel heavy and your whole body exhausted.
For ヒ, imagine being so tired that you can only manage a weak 'heave' of breath: heave -> ヒ, as exhaustion sets in.
