my mum forces me to take birth control

i don’t know if this is the right place to talk about this so i apologize if it’s not.

i (14F) am taking birth control, but my mum is forcing me to take it even though i’ve said multiple times i don’t want to.

about 1 year and 3 months ago, my mum took me to the doctor since i had a “horrible mood”, and they put me on the pill, even though it was definitely just me being a teenager.

since i’ve been taking it my mental health has gotten really bad. it was bad before i started the pill but it’s gotten a lot worse. i’ve said to my mum multiple times that i felt better, happier, calmer when i wasn’t taking it, but she INSISTS that i have a “better mood and attitude” and that i “seem happier” even though ive expressed this is the lowest i’ve ever felt.

whenever i suggest coming off the pill she gets really angry and refuses to hear me out.

does anybody know what i should do? how can i talk to her about this?
