I feel like i can't have a proper conversation. I don't really know if it's really anxiety or I'm just rude and can't hear people out. Everytime I'm out by myself, i feel confident but whenever the cashier asks me 'would you like a bag?' I just immediately cut her off saying 'no, thanks'. I can't help but feel guilty cause all i want is like the normal conversation about her job, the weather, daily life and stuff as she scans my things.
