Yes, you have every right to be peevish today. This will get worked out when others take their heads out of their asses and see how consistent you've been all along. Just be patient, they are dealing with their own loads of shit.
With that said, and a tasty chemical-enhanced oatmeal raisin cookie in what has been your dwindling stomach, I am requesting that the rest of the day you not focus on comfort food, yes? There is no need to sabotage the 18 lbs you've lost to frustration. You have the control, use it here. Think of the joy of looking at the scale tomorrow when it could say that you've lost an even 20 lbs if you eat well today.
This is just a speed bump in your month of power. The radio is being a oracle for you today. Listen to the words. Note that they are about putting yourself in a strong mindset. "Move the heart. Switch the pace. Look for what seems out of place", "I have felt a different shadow on the wall, A stranglehold on a certain feeling", "Pull up your head off the floor—come up screaming, Cry out for everything you ever might have wanted" Listen to these. Do this!
Now, you have work to do. Pretty, creative work. And when that isn't appealing any longer, then you have writing that is clawing it's way out to attend to. Don't be left in the dust just because of someone else's issues. You don't have to take them on as your own. Albatross be gone!
You make the wake. Keep moving.
Lovingly, with a boot aimed at your ass,
