I am new to the forum, but I can relate to these stories of shopping and the anxieties that it can bring.
Generally, I am not very good at keeping myself or my thoughts organized. So when I do venture out to some store (mostly out of necessity), I have a hard time remembering what it was I needed to buy in the first place. As a result, I tend to wander around the store and I have a hard time trying to decide which items I want. Very indecisive.
I also try to avoid the other customers and the salespeople (even though I would very much like to be able to start up conversation with those I find interesting). I tend to be very aware of my physical placement within an aisle or in regards to other shoppers. This is most evident when I go shopping with my girlfriend. I think I spend a bit too much time and effort trying to watch out for both her and myself, making sure we aren't in the way of others. It probably looks quite silly. She is more focused on what we are shopping for and I stay busy keeping track of all the people.
And yet, at the same time that I am "shopping" I tend to sort of detach myself from reality. The lighting within the stores, the aisles filled with so many, seemingly useless items, and the salespeople wearing silly uniforms. These things also make me feel anxious. It does feel unreal. (Perhaps because, in many ways, shopping/advertising/consumerism IS based in a world of unrealities and simulation). Many times I can literally feel myself trying to hold back an outburst of laughter.
Shopping makes me feel paranoid and a bit manic. So when I'm shopping alone, I try to just hold myself together and stay as invisible as possible. When I am with my girlfriend, however, I tend to spit out all sorts of stupid thoughts and jokes that probably don't make much sense. Probably some sort of defense mechanism.
As I type this, I am trying to prepare mentally for a trip to the market later this afternoon. All I need are a couple of food items and yet somehow I feel as if it's some huge operation.
Anyway, I hope somebody finds this insightful. I am new to this sort of forum/posting thing, but I am hoping it might help me and others. I would welcome the opportunity to share experiences/ideas with others...beyond just the shopping experience, of course.
