Yep.
I was just in Lidl. This is the worst supermarket because I always get particularly anxious. It feels like you have to move all your stuff to the bagging area pronto and pay at the same time as putting your shopping away! Ahh!
I get worried about forgetting anything as well and I always take ages choosing things - Has to be the yogurt pot without a crack in (I accidentally bought one and now I don't wanna eat it!!)
Going with someone else to the shops makes me anxious as well because I feel like I take too long and I'm so indecisive. I worry they get fed up and think I'm crazy.
I too go to the shops regularly and it doesn't seem to get better but then I don't think I really do anything to stop the thoughts that are making me anxious. Sometimes I am in my own little world and I block out the fact there are other people that could be looking/judging me. But that doesn't always work especially if I drop something because I am so clumsy! :(
I find just focusing on what I need to do helps but I usually get distracted by these silly thoughts.. Though I think it's rational to choose the item in the best condition because of the money.
I rarely make eye contact with staff or even know what to say to them. My boyfriend chats to them and I just think whats the point they probably don't care or want to talk to you but I'm sure it probably makes their day a bit more interesting and makes them feel like a human being rather than a cashier robot.
I think I have almost had panic attacks in shops because there have been too many people around and it's felt like I can't get out.
