My advice is different. Don't sew. Don't find a small project like a mug rug or potholder. Do other things. Spend some time looking through old photos. Find a good cookie recipe to bake. Get the family involved in a huge jig saw puzzle or a board game. Tell yourself you are not allowed into your sewing space until Wednesday. If the weather gets better and if your health allows, schedule a few walks this week.
Don't feel guilty about anything.
