Me(23M) and my Gf(21F) are in relationship crises

Actually my girlfriend's family got to know about us from third person which was the main reason of the crises. That person was not very happy about us.

After her family got to know all the things, they restricted my gf to talk to me by giving various swears. Now we haven't talked since 3 days. I am in full panic because i have an idea that her family is super strict and they won't let her be with me and this was not the ending we were supposed to have. I am genuinely so attached to her i was so much committed to her.

But in this situation if i reach out to her, more issue can be created because her family is not so happy with her. I am not able to concentrate anywhere in life currently. Everything is just messed up and don't know what should I do further here.

What should I do in this situation ?
