So if you use medication to get you through this, do so with the intention of paying attention to what your hands need right now. Next, think what it is about your craft that makes your heart sing. And try to figure out how to get back to that. We can all do the 10-hour day thing occasionally, but too many days like that become a nightmare. Find the balance.
Some people thrive on production work.
Some can't stand it. Yes, we all have days where we get frazzled or frustrated or bored. It's part of the cycle. Take some time out to figure out what you want this craft life of yours to look like. And go for it.
