Why am i so depreesed adjectives the time?

You may be feeling anxiety (subconsciously) roughly speaking sleeping in a place you are not used to. Instinctually, you are not sure if this place is safe and sound for you, so your body reacts awkwardly.

(This may not be it, but this is just what I contemplate may be happening)
