Not sticking to meal plan

I am writing because I make a plan to follow my macros and then if I’m tired or overwhelmed I abandon my plan. I’ve made some progress in my weight release but keep having these glitches. Like packing all my healthy food to a party 3 hours away and then eating the food there. And at that party having some cake and not sitting down and eating it and not really paying attention to how much I’m eating. I seem to have more trouble around disagreements with my spouse, the full moon, and my period. I’m like so committed and gun-ho. I say I want the results and then do another action. I’ve used the model and it works but I keep fluctuating and I ‘know’ I could meet my goal and I keep self-sabotaging. Thank you.
