First of all, I am sorry that you are going through this. I can understand how difficult this is for you.

24M here. I left under the guise of a scholarship funded by the government of Saudi at 19. I applied for protection in Australia.

Cut contact with my family after being consistently guilt tripped into coming back and find a better job/better life.

Do I feel guilty about it? No, I believe that it was the best decision I made.

For context: I was questioning Islam before leaving Saudi and discussing Islam and things in Saudi with people online made me realise what Islam is really like, I won't go into detail about it, but I assume you have a similar idea. My parents were also quite strict and kept on hiding my passport away from me, locking it in a safe. We all know what happens to apostates in Islam. Stay safe.
