If you live at home and your parents are against The Craft, take a page from hidden Christians and use your closet as a makeshift altar room. Flameless candles, altar cloths, statues, and crystals can ask blend in with normal items in a room and be taken into the closet for practices.
If you can do your practice in your room, that’s obviously better. 
Meditate. Meditate. Meditate.
Meditation helps strengthen the parts of the brain that make us feel connected to The Divine, Mother Earth, The Lord and The Lady, or whatever you may call the mysterious unknown.
Passion can be energized by hearing/reading the amazing stories from others that remind you this isn’t some dumb fad but there’s something real behind the curtain of rituals and practices. We just read the story of a person this week that can feel energy and if it will go bad or good and how they used that to avoid certain death. These kinds of stories aren’t for the people that experienced them - they’re for the rest of us to remind us what is true.
Finally, as much as is possible, stay active with a group of like minded people. We’re on Discord. We’re on here. They started a book club and weekly challenges. There is an upcoming group ritual. There’s daily affirmations. There’s so many ways to connect and through those connections to be lifted up.
Remember: You are a light and you deserve to be lifted up as one by people that understand and care about you.
