we live with our parents and theyre not homophobic( they have no hate towards lgtbq people and they don't care), but theyre very against the idea of their own childrens becoming any sort of lgtbq. I understand this concept of theirs. I feel very guilty to my Parents, whom I am going to be keeping this secret from. My dad has told me many time to tell him everything and keep check on my siblings and report if there's anything like this going on, and I am conflicted because I know instinctively that I should not. Ive already told my sister that I accept who she is, but I cannot openly support her mostly because I am a coward and im scared of my parents... I dont know what to do. Im very scared now that I know she is bisexual. I know that she will be miserable keeping this secret too. I am just so afraid that there will be one day, she will be suicidal even because of the pressure in our house. She is also too young to leave or make her own decision. How do I go about this, please help me!

-sincerely a very cowardly older sister who just got dumped a big heavy secret
