Oh what a pity. So sorry about your goat. I know you will miss.
About your mom, I know this is not a good moment but you can't blame you for not being at her side. She is not alone and you have your child. I know is hard being far away and feel that you can't help, but feeling bad is not going to be so helpful too. I don't know if you know what I really mean. My little English doesn't allow me to express as I would like to help you but PM if you need.
