Thank you so much for all your lovely and supportive comments. It's so nice to know I'm not alone and many of you feel the same. I am feeling much better now. My dissertation was handed in on Thursday, the last of my custom orders were posted yesterday and I feel like I'm more on top of things.
Having said all that, I do want to take a break from making to sell and focus on making for fun. It may be that some of the things I make for fun end up being for sale but that's not going to be my main aim for a little while.
So the shops will stay open but anything that gets added will likely be one offs. No more mass producing for a while (if ever again!)
