Help

I am turning 14 soon and I have a secret, I am bi. I haven't told anyone yet either. I am afriad to tell anyone too. My family and friends are against bi-sexuals so I can't tell them. My dad and sis might be ok with it but my mom is stronlgy against bi-sexuals and she might think I am disgusting after I tell her. My friends think it is just nasty to be either gay, bi, or lesbian. That means I will loose my friends too. What am I supposed to do?
