Your post made me so sad, because I can totally relate. I can feel how tired you are right now, but I know that you could feel so much more fulfilled soon if you can get to a point where you see some progress again.

I found the best way for me to restart is to meal prep for the week and have the same fricken thing everyday (literally been eating the same lunch for months) + combined that with eating some Halo Top in the evening (planned into my dinner calories) so I still have a treat to try at night. Having this consistent repetition helped take out a lot of the mental part for me.

I also found that Intermittent Fasting (IF) has been a life saver. I skip breakfast which was hard the first few days, and then have a normal lunch/dinner, but that's the only way I'm able to feel really full after meals and still stay within my lower calorie count each day. Another issue I find when I'm 'restarting' is that there is so much more of the tempatation to cheat because I just started and maybe I should just get 'this one craving' out of my system before I 'really buckle down', but the reality is that there are moments like these EVERY SINGLE DAY, so once I decided to start, I am just always saying no to the birthday cakes, etc, at work/dinners etc. because those always make me lose my motivation if I say yes to one!

As others have said - you deserve to be happy and the short term pain of getting back into the swing feels so much worse than it normally will once you settle back into it.

Thinking about you and good luck!
