I know how you feel. I keep an inner dialogue going in my head to try to quiet my instinct to speak my mind.
I think there is an anti ***** medication. My psychiatrist put me on one.
And no matter how bad those mashed potatoes may have been, you were not at my house when DH was out of town and I wanted to try a nutritious substitute for potatoes.
You are probably aware that cauliflower is a good substitute? Not the way I made it. I must have overcooked the cauliflower. It looked like gray gruel. Of course I tried to serve it to my children.
I will never live it down.
Switch your AD. And never let me in your kitchen. I hope your mood gets better.
