How can I observe Ramadan with unsupportive parents?

Salaam everyone! I know Ramadan is still a bit away, but I’m already thinking about it because this is really important to me. I’m a revert Muslim, and I live with my parents who aren’t really on board with my practice, so I have to be low-key about it. Weekdays might be okay since I’ve got school and a schedule, but weekends are tough-I’m around them all day and they’d totally notice if I’m not eating or drinking. I’m trying to find a way to fast without causing a big issue at home. I’ve been wondering if I could just make up the weekend fasts on weekdays, but I don’t wanna do it wrong. Has anyone dealt with something like this? Any tips on balancing Ramadan, family stuff, and staying safe?
