Heidi, no-one thinks you're thick and I hope you do come back. I know you've done your research (although I don't remember you mentioning you'd had goats before when you visited us) and you asked advice so I know you prepared well.
I kept my first goat on her own to start with, not intentionally but I had bought two with a friend, and was keeping them in her garden, and she then decided she didn't like the white one so I could have her and didn't have a lot of choice other than to end up with no goat at all. As the goat lived very near the house, she had people around most of the time, and the dogs, so didn't seem to suffer but is much happier with company.
I think Willow is a lovely name too. My son had a rat called Willow once. I am intrigued though that she is a GG x Tog but is white like a Sanaan.
