Everyone needs a good vent :) I'm in the same boat as you. I've dropped about
85 pounds since late February and I love my food but it don't love me back
Every holiday I've been in a flare for the past year, including my birthday and haven't been able to eat my favorite foods so I lived it up today even though I'm flaring...I'm paying for it now but it was worth it! Maybe you could try just eating that one comfort food you love in a small portion to make you feel better(at least for a short while).
As for the emotional distress I completely understand! Prednisone is horriable. Today I am officially down to 50 mg of Prednisone and I just tell myself that the side effects will eventually go away. Don't you hate being moody all the time and feeling bad for blowing up on people? It can be hard for loved ones to understand if they don't have the disease or take the horrid medicine that comes with it but that's what we're here for!
The physical side effects will go away eventually
