Spells do not require ingredients to work, it's all your visualization and ability to focus the energy. Items can help a spell, but they do not make or break one. If you wish to cast spells, you can do so on your own. You might also wish to consider raiding your pantry for items that can be used in spells, or walk around in nature and find things.
Meditate and ask your guides to help you find your powers within. Intention is a very strong tool. There are many things you can use. I made my wand staff from a branch I found by the lake and added to it with jewelry supplies I already had. It's difficult when family members do not accept and understand. Keep following your path. You will find a way. Stay true to who you are no matter what. I wish you all the best on your journey of discovery! :)
