My mother had heart reconstruction surgery three years ago. It was so hard for all the family. Two days after Xmats. My worst one. I understand how you feel.
And about your goat something like this happened with my dog several times. i scared of driving. Simply i cant. My dog have some back problems so sometimes the pain is so strong and She does not move. Only my husband can take her to the vet because is in another town and i cant drive out of my own litle town. So i know how you feel but web can't let your anxiety stop our lives. Just breath and have a little look. Or have you got any neighbourgh who can help you and look At your goat?
