Aw, I completely understand how you feel, Nicole. I have had many of those days too, where it all just seems to pile up.
Here is the good news: YOUR SHOP IS WONDERFUL!
And....YOU are the boss.
As a mom and an Etsy seller with a part time job outside of the home, it took me a few years to not feel like I had to scramble all day, everyday, but my best advice is to set working hours. It has made all the difference for me. Even if it is just taking one day off, away from Etsy or not checking in after 6pm. I take Saturday afternoon and Sundays off (yes, I know, it is Sunday and I am on Etsy, lol, but forums are fun, not work ;). Because I can't ship on Sundays, it makes sense to take that day off just to focus on family. I do answer convos over the weekend, but that is usually pretty quick.
Another thing that has saved me when I am feeling overwhelmed, it to put my shop in vacation mode for a few days or even a week. I do this a few times a year when I am feeling burned out. It hasn't seemed to hurt my sales or SEO ranking at all and even if it did, it would still be worth it to be able to come back fresh and enthused again.
Sounds like you yourself are a SUPER MOM! Take today to enjoy your family and have a wonderful, peaceful Mother's Day!!
