Help? I’m sure I’m bi and like this girl.

First off, I live in the most sheltered part of Utah, which is pretty much Mormon country and 🏳️‍🌈 is condemned and pretty much not talked about. I used to be really really sheltered before my dad left the Mormon church and my parents divorced.Then, in 7th grade, this girl came out to me as bi. We had already been friends and I was honest about not being all Mormon. That’s why she told me, and I was the first person she told besides her sister. We kind of became each other’s confidants that we could actually be honest with more than other friends. She was the biggest reason I became interested and started exploring my sexual orientation and what I liked. I got curious, then over the summer we where together at a summer camp for 3 weeks. I developed a ginormous crush on her and realized I was bi too. This year we have had 2-3 classes together and I still like her. She has anxiety ad some depression, and her parents aren’t supportive or believe her. Recently she came out to a friend who told her she didn’t like lgbtq people and didnt want to be around them. I think she might have feelings for me, and I’m also trying to keep our friendship and help her through stuff, like she can for me. Here’s the thing tho;she doesn’t know I’m bi and I don’t seem to have the guts to tell her. This is really long, but HELP???!!!
