How about repurposing your sewing room ~ call it your 'get away' room. Don't let what you haven't done get you down - reflect on all you have done each day. Take time for yourself, just sit and enjoy your fabrics - like you would art in a museum. Play some favorite music & get lost in yourself.
Trying to do things when we are stressed & tired just compounds the problems. Let yourself know it's ok to be a fabric collector at this point in your life. Time will change things I bet
