Coming out

I'm not sure what to do. I think I'd like to come out to my mom. My family is very liberal and accepting, but my mom is constantly saying things like, "LGBTQ+ is a trend/fad" and "all these kids are just going through phases". I'm worried she might still think that about me, even thought she'd never say it to my face. I'm still questioning, not sure if I'm bi or what. And I feel bad for saying this, but I'm afraid it will just be another phase of mine. I'm not sure about anything. Should I come out? And apologies if this offended anyone. Thank you. 🤗🤗
