What have you got to lose!? Even if you fear that your amount of sales may affect people from buying you, keep trying and bring those sales up! The sooner you get your butt in gear, the sooner things will pick up:). I don't think people necessarily even look at that. If I see something that I really love, I don't care how many sales you've had and I've seen plenty of shops with really cute stuff who are on vacation. Life happens. I think you can make it work (as long as you put your mind to it!). Good luck and welcome back:)
