I know this is a very subjective question, but... should I continue writing?

Over the last few days my faith has been wavering and I don't know if I should continue writing at all, or not... I feel like my stories are no good... don't even get comments of any kind anymore... yeah, I know they have a slightly darker atmosphere than most stories, and not everyone enjoys that, I understand. But in the past, at least I received one or two comments... so I just wish to know... did I get boring? Cliché? Too dark? Or people are just busy and my chapters are admittedly quite long...
