My goat seems depressed

[Church Girl]

Hello everyone! I have a goat named Little Mama that we got around two years ago from a little homestead. She is a super sweet goat. When we first got her, she came with another goat, Lucy. They were both pregnant when we got them and Lucy gave birth to two kids...but Little Mama never gave birth. Before Lucy gave birth they were buddies but now I think she is jealous. Then, like a year later they both got pregnant again and, like last time, Lucy gave birth to two kids and Little Mama gave birth to two as well but one died soon after birth and one was already dead before it was even birthed.

Now she basically just stays by herself and lays down and naps more than the other goats. Is there something wrong with her health or is it just her being depressed? She is still pretty loving to humans, just not with the other goats.
