battle to get on birth control please help me

After this I locked myself in my room because I was scared. They think I wanna have sex with my boyfriend but I don't I'm really scared they're gonna make us break up. I can't talk to anyone in my family they all freak out with everything I do. Instead of them teaching me safe sex they're teaching me abstinence I don't even wanna  have sex right now but I just wanna be on BC just in case I do I'll be safe. Ps this is the text messages between my sister. I was talking to my mom in person asking if she would put me on it and then she told my older sister I wanted to be on it and this is what it resulted in. I don't even know what to do at this point someone please help me I regret even asking for it... all I wanted was to be safe 😕
