Accepting Islam and concealing it from one's family

I converted to Islam. However, I have kept it from my family knowing that they will not accept my newfound religion and because of all the negativity about Islam in the news. Chinese people, including my family, are very close minded about preserving their culture and religion. But It's taken a really huge toll on me mentally. I'm not too fond of hiding my "new self" from my family and I think it really strains my relationship with them. I always have to lock my door when I pray and I always have to sneak out with the hijab or put it on when I get outside, which is a very difficult task and I think them not knowing somewhat hinders my full potential as a Muslim. For example during Ramadan, my mom would reprimand me for not eating and make me eat and etc. What should I do? Should come clean knowing that they will disown me or should I continue to keep it to myself?
