A very warm welcome, @reyna! 
I personally don’t know much about Vodou practices- but it sounds very traditional and fascinating! Looks like you were able to complete the spell with some advice from your sister- how did it go? I hope it all went well! 
Feel free to make yourself at home here in the forums- you are very welcome to jump in on any topics of interest, teach what you know (I’d love to learn more about Vodou from you, if you are able to share!), join the current challenge, and participate in the weekly group ritual.
It is a pleasure to meet you- Blessed be!
