Great suggestions, I would also make sure you are getting enough sleep. If caffeine or other drugs are keeping you up, try and phase them out and see if you can go to sleep instead of staying awake worrying. You don't mention if there has been any changes in your life but it's normal to react to a significant change (e.g.death of a relative or close friend, end of a long term relationship, loss of job or other significant financial setback, etc..) with stress.
To each his/her own. The popularity of the site contradicts your view. I pay more for handmade item as they are usually one off and I can see value in owning a unique item.
I clarified it later on: I was not talking about the artsy/individual stuff you'd find on etsy, but about repetitive production like weaving baskets or carpets.
