Everything & nothing

Idk what to do. I'm bi but too afraid to come out because my family is homophobic and religious. and that's just one more thing to add to confusing shit. Religion doesn't make sense to me so I can't accept it. If I said any of this to my dad he would freak. He brings God into any conversation. He was pissed when we passed a church that had the pride flag and we don't even belong to that church. I wanted to tell my mom all this hoping she could help me out but I couldn't even do that. She was diagnosed with breast cancer five years ago and almost a month ago now, she lost her fight. That was extremely hard and still is. I don't open up to people or talk about my feelings. I haven't being going to school consistently and I'm failing, or close to failing, a lot of my clases. I'm only a sophmore in high school and ik education is important but I just don't feel like doing anything. I wish I could hide under my blankets and have the world go away.
