My abusive homophobic parents have been threatening to kick me out if I turn out to be gay (which I actually am) since about a month. 

Many people at school know I'm gay (My friends have been supportive, most of them are gay too, but I'm too afraid to tell them about my family problems) and I'm worried that my parents will somehow find out.

I've been avoiding discussing anything related to that with my family but the topic just comes out and I cant help but defend lgbt people.

 They've also been threatening to track my internet activity. 

I've gone as far as to tell my parents that I like certain women just to make them think I'm straight 

My parents pretty much already dislike me and have done everything they can to make my life hard since the last month, coming out as gay to them would mean I'm completely dead.  (They just won't kick me out yet because that would get them in trouble with other people, it's hard to explain) 

I'm from Mexico btw, in case that's relevant
