So two years ago my sister suspected I am gay so she confronted me and I denied it... But since that dreadful experience there has been certain tension between us... Unspoken disgust from her part, and anxiety from my part. So today she sent me a video of Obama saying that he proudly accepts gays and Muslims to serve in the military. I replied (on Facebook): Bravo for Obama. She replied back: Bravo for what? So I said jokingly: well I am pro-gay and pro-Muslim, sweet sister... And then she said: don't you dare call me sweet sister if you are pro-gay, and tell it to your poor mother so she can be ready... I just replied back with WTF, and hahahahaha. But in truth I am terrified. She opened a traumatic experience that we both left unspoken for couple of years just like that. For what she knows I might have been ironic, which I was, but she took it to be very personal. She is a very angry and bitter person, and she has a lot of psychological issues, but I love her no matter what. I just fear that she might destroy my life...
I don't really have any experience with this situation at all, but if your family are homophobic, maybe you could try talking about LGBT rights every once in a while? You might be able to open up their minds a bit more, and hopefully you would be able to be more comfortable in your own home. Maybe you could try talking to your sister as well to calm her down? I don't really know what advice to be honest... I hope you are feeling okay now
