I have hit a rut and it's depressing

I went out to a few bars in Naples (Italy) over the weekend. When I've been out in cities in the UK and Germany in the past I'd get approached by women, which is good for me as I haven't approached in over 10 years as I know it will be a guaranteed rejection and won't go well anyway, so I don't bother. However, this didn't happen at all this weekend as I wasn't approached once.

My last date from a dating app also told me that I didn't have a connection and this kind of summed up the kind of luck I've had lately. I also haven't had any replies from some openers I sent on apps recently which also sums up the hopelessness of the current situation.

What suggestions do you have?
