I have a tendency to "pick" along with other SI stuff.

For my feet, I have tried to care for them rather than pull at the skin. I have a Saturday night ritual, of soak, remove hard skin with file, moisturise then really bright nail varnish. It takes my mind off other stuff and the bright coloured toes help to remind myself of my feet on the ground - the brighter the better.

Hope you can share it with your T.
