I eventually realised that this wasn’t really enough and I needed to get out more. It was quite easily solved by a bit of retail therapy, even if was popping out to the supermarket, going to buy some makeup, shop for clothes, etc.

It certainly helped me with my confidence anyway. You already have the answer, so as you said – just do it. A bit of retail therapy might do you good, even if it’s only browsing. Getting out and about amongst other people was the important bit for me.
