Worshipping Hecate

Hello everyone! So basically, straight to the point. I have an altar for Hecate I've been Worshipping her for maybe a year? But I live with my mom and she's a Christian. I don't want her to know about this because she wouldn't accept it be for real. So I can't really give obvious offerings, I can't do some spells (she often complains about the smell of smoke) and yeahhh I have a big altar and a statute of Hecate but she thinks I just like greek mythology so it's okay. OKAY, WHAT I REALLY WANNA ASK: can I just wait to do the spells and shadow work until I live alone? I thought about just praying to her and giving her offerings you know, and later on when I'll be able to do this practice more openly when I live alone or something I would do the deeper things like shadow work and spells. I think it's okay to wait but I just wanted to ask what's your opinion on this. Thank you so much for reading and I would love to get some replies because I genuinely don't know..
