You sound like you're being torn in 50 directions at once. When my boys were younger there were long periods of time where I found myself directionless and having no time creative-wise. It happens. But then often something else would happen, helping with an art project, making costumes for school plays....it's all creative and felt great!
Let yourself know it's OK. You don't sound like you want to leave music or glass but it's OK to take a break and explore other mediums while you raise your kids.
When my kids were older I had three rules and then I could go be creative. Food in the house? check. Toilet paper? check. Does everyone have some clean clothes? check. My job was done.
