first time venting online also what do I do?

So hello! Fénix there and I am a 15 year old transgender boy. Right now what's troubling me is that my girlfriend, (who is 12, I am strictly against M.A.P.s so don't think I am one) who I only know from the internet but have face-timed many times before, has today came out to her parents about her being trans as well and she also mentioned she is dating me. The problem is with her parents, who are unsupportive and ungramatically said that she is ''full of sh*t'' or that she is only transgender because of me. That is of course not true and just proves that her parents are driven to hate and are really uneducated. She said they may limit her from using the internet (they limited her entirely for 2 days or so now) because of her being trans and I am now scared of what they might do to her outside of reducing access to the internet for her. She also said she might consider hurting herself because of how her parents treat her, even though I told her not to. Is this the dead end or..? Should I not be worried?
