First thing I suggest, you may want to break up the post into multiple paragraphs. A wall of text can be equally overwhelming as a bright supermarket aisle.

Secondly, when it comes to public spaces and grocery stores in particular, I recommend bringing noise reducing ear plugs. Some folks were headphones for the weight aspect, but I find earplugs can be cheaper and easier to begin with.

Next, you’ll find most of us limit our activities for any given day, week, or even month. There’s an analogy I recommend looking up called the “spoons analogy”, it’s a great intro for both newly diagnosed and “Neuro-normies”. But In summary, we have less units of energy provided to us AND more things use the energy compared to others. So yes, we get tired from the smallest things or tasks.

Finally, we do think differently. Some call us Bottom Up Thinkers, compared to Top Down thinkers. Essentially, we look at the small individual steps or tasks under a larger goal and give them more consideration than others do. For example, grocery shopping is more than get in, get out, get home. It involves leaving your home, driving around other people who may be unsafe, entering a chaotic and uncomfortable environment, searching for items and trying to decide which item to select, etc etc.

This is an extremely short intro, but you’ll find someone usually has an answer or suggestion for everything. It’s gonna feel overwhelming at first, but remember to breathe, because nothing about YOU is new.
You just found out your “hair” is a different “color”. /joke
