C-PTSD Symptoms. Due to these events?

I know a person can not be diagnosed here like this. But I just want to know the possibility. My girlfriend has a very restrictive family. She was living at hostel when her family found out about our relationship! They directly went to her hostel and took her back home with them. She had no idea what or why it was happening. She got her laptop and phone taken away and she didn't get it back until 3 months passed. She has been restricted at home for more than 2 years now. Her career is over because her family doesn't let her go anywhere! They keep tabs on her all the time. They check her phone/laptop regularly and she is not even allowed to lock her room. She is scared all the time, she always feel paranoid. And she has every symptom of C-PTSD. But can it develop due to these events? Her family is very strict and abusive(verbal), they body shame her, call her ugly for being dark skinned and so on. She can't go to therapy or even mention that she might have mental issues to her family.
