Confused

I’ve had this huge crush on this girl from school and lately we’ve gotten pretty close. She told me that she likes me and I told her I liked her too but I’m not out yet. I’m scared to come out my parents are really religious and do not support the LGBTQ community at all. I’m scared to come out because of what others might think. I’ve been with guys before and I know I’m bi I’m just really scared to come out, please help
