At my worst, and this was a long time ago now, I was housebound and when I showered, I sat on a plastic stool and my mother would have to wash my hair because I didn't have the energy to lift my arms above my head. Today, I run at around 40-50% capacity which is a vast improvement. If I don't do too much and schedule rests and proper sleep patterns, I'm good. If I was more vigilant, I'm sure I would be around 60-70%, but running a small business is a lot of work and I don't always have that luxury.
