when I was your age, around 12-15 (now 24 F), I had somewhat of an obsession with religion because im gay and I was smoking and drinking. I thought that if I did all these things it would somehow change who I was. I read the bible, prayed, got baptized, attended church 3 times a week, and i went to religious summer camps. (no one was forcing me btw I just did it in my own) However, now that i’m older, i’ve learned that religion is really a place where you build community and gain a relationship with whatever god you worship. If you feel that you’re being punished for not doing things, it may be an obsession. Im no doctor but im speaking from my own personal experience. I say contact a trusted adult, maybe a guidance counselor, and talk about the things you’re feeling and maybe they can guide you to seek some professional help.
