homophobic mom

context i am extremely closeted

me and my mom were talking about the LGBTQ+ community and she said a bunch of mildly homophobic shit and then compared been gay to doing drugs saying that she doesn't need to try it to know she doesn't like it and i am just sitting there thinking nothing after that i just left, i don't know what to do i really wanna come out but i she's the only one in my family (that i care about) who is kind of homophobic so i don't know what to do
