Maybe a silly question?

My husband and I are visiting a friend in Japan early next year. I’ve only just started learning very basic Japanese and wanted to write the translation of my name. I’m called “Shay” that’s not a nickname, that’s my whole name. But when I’m trying to translate, I can only figure out how to write シェ(shee)?? Would that be right? Or シェア (Shea) which I think means ‘to share’ ?? Is there a way to write my name that doesn’t sound silly? Is there a translation for the Shea tree flower that I can use? I’m at a loss. I’m sorry if my question is dumb, I’m trying my best
