Assalamu Alaikum - My parents make me go to their church and it keeps me from Salah

Assalamu Alaikum. I’m a recent convert to Islam and I’m stuck in a really hard situation. My family forces me to attend their church services and I can’t leave - I’m still a minor and have nowhere to go if they kick me out. This isn’t a normal church: it’s very tight-knit, they track who comes, and there’s a leader the congregation treats like a “messenger” and even elevates alongside God and Jesus. My family has been part of it for generations, even with priests in the family, and I’m sure they’d disown me if they knew I’m Muslim. For context, I don’t follow their religion because members have to pay money twice a week and there are other serious problems, including pressure and violence toward people who try to leave. Ever since I accepted Islam I’ve tried my best - I set aside time to pray, I study the Qur’an as much as I can even though I don’t know Arabic well yet, and I avoid food that isn’t halal. But there are things I simply can’t do around my parents without getting into big trouble: wearing the hijab (I try to cover with hoodies when I can), leaving the service early, or praying where they can see me. Because of that I miss some prayers - usually Maghrib or Fajr depending on the timing of their worship service - and I feel horrible and guilty about it. My main questions are: Would Allah SWT blame me for missing these prayers when I’m forced to attend? How should I repent for the missed Salah and when is the best time to make them up? Also, would Allah be angry at me for disobeying my parents by choosing this religion? I’m trying my best under a really difficult situation and I’d appreciate any practical advice or comforting words. JazakAllah khair.
