Sorry for your loss. Make an inventory of everything you can remember in your sewing supplies including fabric, marker, thread, pins and etc. Make notes anytime you think of something lost include anything in your home or RV. This will help the insurance company. As you list items include the cost of replacing each item,(not what you paid). For mental recovery I can tell you go ahead and cry all you need too. Grief comes to each person in a different manner. Don't fight grief it ia a natural process of healing. If you feel counceling would help don't be timid about asking. Prayers for you and your familhy.
