This type of thinking probably occurs in a lot of people’s minds but I can tell you that is an absolutely useless thought train.
I’ve been recovering from a pretty deep chronic depression for a while now and I can tell you that it was exactly this sort of negative ‘what-if’ thinking that held me back.
It’s basically mental automutilation. Nothing but drama created out of thin air to create a “comfort zone” of melancholy, because having something to fear or dramatic about is at least familiar and defined instead of stepping into the unknown all the time.
It’s a negative perspective when you could also be looking at it from a positive perspective, like: Hey I tried this thing for months, it didn’t change anything for me, I have learned something from this, I can share results and see how others have maybe fared, even if the results aren’t positive per se. It’s something you would not have known if you hadn’t tried. They add a tiny bit to the bigger picture.
And when it comes to diet or supplement trajectories… having one or two cheat days in a time period of months probably doesn’t ruin your whole effort. Just pick it up again it’s not gone to waste.
I know it’s hard but try to live inside the ‘here and now’ more instead of worrying about the future or the past all the time.
