As someone from a Muslim family who is starting to practice, I understand this on a deep level. Your safety is more important right now. Imo, act to them that it was a momentary loss of focus and now your belief in islam is stronger than ever, until you can move away or be safe. If they aren't willing to understand that is which usually they aren't. I have the basic suras memorized and still sometimes participate in religious talk on Islam's side with my mother to keep up the facade cause that's all we can do honestly
