I'm bisexual but my parents are southern baptist, any advice on how to tell them?

I'm 21 years old but I'm still living with my parents trying to finish my college degree. I'm just afraid that if I tell them I'm bi, they will kick me out so i wouldn't be able to finish my degree. I've been bi for about three years, but I have suffered from depression because I haven't been able to tell my parents because they wouldn't accept me if they knew. They recently took me to a psych for my depression, but I didn't feel comfortable talking about why I was depressed because the psych has the same beliefs as my parents. They have told me that they will love me no matter what I do with my life, but I know that if they found out that I'm bi, then they definately wouldn't. I'm scared, but I'm willing to do what it takes to get this off of my chest. Thanks in advance for the advice/help. :-)
