I would suggest finding some gear to make yourself look more like a bunny. You could also hop around like one too! And depending on what kind of bunny, you could adopt that diet. If it's safe to, maybe eating some bunny treats too. Just as long as it's safe for your body. Some vocals could help too, along with connecting to others like you. Community often helps with euphoria. I also suggest buying clothes to help with euphoria too, if you can afford it. And you could also make a nest. For one in your room, you could lay a blanket down somewhere and line it with more blankets and/or pillows. You could also make one outside. For one outside, you could use freshly cut grass or dead leaves for padding in a somewhat private space. You could also bring enrichment toys into it. If you wanted to buy bunny toys, you could say its for a friend's bunny! I also suggest doing crafts too. Maybe making a bunny paw or painting one. You could also draw what you want look like. As for a bunny tail, large pom poms may work. Hope some of this helps! Don't be afraid to reach out and ask for more tips!
