Hey welcome to SOM Nayamei!!
First up don't worry or make a fuss to obtain tools,magic is not about the fancy tools you can use.People use tools because it helps them concentrate others because they just prefer to.
Just relax the key ingredient for any practitioner of the craft is belief in thy self and not some fancy store bought thing.
Learn the basics and when you are ready try doing a spell.You don't have to have any tools just belief(key ingredient).Also you can always get tools.
Your mother well I won't go running off to my mum to tell her I was a wiccan especially if she is a christian woman.First you should make sure that this is the right religion for you and that you are committed to this path.If it is yes then you need to ease her into it.Bring up the topic and hear what she has to say.Talk to her and say you were doing some research since it was interesting and so on.
Now mind you when I told my mother that I was going to dedicate myself to the craft she did not like it all that much.I just said it straight no easing her into it or anything since magic is a big part of my family no explanation was needed it was just not a path she wanted me to choose.
Anyways I wish you all the best.May the God and Goddess shine their light upon you.If you ever need someone to talk to I am usually on here.
