Anxiety asbestos in toys

My anxiety over asbestos in childrens toys has sent me in to a complete spiral. My children have done several dig kits. Due to the nature of digging out the toy the substance has been blowing everywhere and created a fine dust. Im sure on occasions the dust has been in hair and on skin and everywhere. On one occasion it was done outside because my son was enjoying all the smashing and bashing of the fossil thing. He bashed and smashed it to pieces until it was fine dust. I am now in a complete and utter state and have had to go on medication. Despite the medication I am completely distraught. I cant eat or sleep
