So I am a teenager and I've thought a lot about my identity and reached the conclusion that I am Bisexual- I haven't told anyone but my closest friends and I want to tell my mom (or both parents), but I'm afraid that she'll say "it's just a phase". She's fine with other people being part of the LGBTQ community but I don't think she's ever thought of her own daughter as being a part of it.

What should I do?
