Everyone goes through slumps. I've gotten some of the same comments that you have and I don't let it worry me anymore. Everyone has a passion. It isn't defined by a label such as quilter or sewer. It isn't defined by the number of finished projects. It is defined by your enjoyment. My favorite part of a project is always the beginning. The middle is busy work. Once the project is finished, that's great but by then I'm already starting something new. I'm sorry that you are stressed. Just give it time and don't let others stress you out more because you aren't in the sewing room.
