How can I support my friend who is going through a tough time after embracing Islam?

My friend and I are in our last year of high school. She embraced Islam two years ago, all on her own, since her family is Christian and they didn't allow her to visit the masjid or anything related. She took her shahadah and was so happy at first, but it's been hard for her to practice properly while still living at home. A few months later, during Ramadan, her parents found out she was fasting. She tried to tell them she was just curious about Islam, but they got really upset and shouted at her. They said as long as she lives with them, she has to follow their faith. Since that happened, she's been having really low moments, thinking about how her family reacted. I always try to be there for her, listen when she needs to talk, and stand by her side, but lately I feel stuck. I don't know what to say to cheer her up anymore. I just want to see her smile again, insha'Allah. She plans to tell her family and friends about being Muslim after we graduate, but the thought of it scares her so much. It often makes her feel down and she's been feeling this way for a while now. She tells me life feels pointless when she can't practice her deen freely, even though she tries her best in secret. She says she's just exhausted and drained. If anyone has advice, how can I help her feel better?
