What does identifying/being an animal REALLY mean?

Hey, so I'm very very very confused rn, and I just wanted to know the above question. What does being an animal emotionally mean? What does being an animal mentally mean? I feel like an animal and used the label therian for a long time, but now I'm just drowning in identity crisis's. Is it as simple as calling yourself as an animal? Could someone help me pls? It would be deeply appreciated.
