One of "those" days

Depression sometimes comes in waves. I'm currently getting hit by the kind of wave where it always seems cold enough to be bothersome everywhere I go and no matter what I wear. Everyone speaks just loudly enough for it to be overwhelming, no matter the topic or who the company. Every positive step forward has a push back and every push back is a blow. All I can think to remedy it is to curl up into bed, lock the door and turn off the light till it washes over, however, having a 4 year old, a job, a significant other and their mother (who is a fantastic human btw) makes for constant interruptions. Waking up every 2 hours because of nose issues or blanket tangle problems has made sleep similar to treading swells: dark, exhausting and relentless.
This too shall pass, yeah? Hopefully before I drown.
