I am going to buy a new phone soon, and I’d like to sell my old one to make up for it by a bit; if I’m lucky around 200 to 250 euros.

I’ve already sold phones on there (well the equivalent in my country) but I was always accompanied by a family member. This time they’re not aware so if they still aren’t by then I might have to do it on my own.

But I’m autistic and have had extreme anxiety forever so this is putting me off, yet I’d really need the ~200€.

I keep thinking of fake cash, being stolen, people being violent for X reasons… I know the first thing to do is suggest meeting up at frequently visited places so there are people around, but still. Is there anything else I can do? I know the other things as a buyer, like check if everything is working etc, but as the seller??
