I am atheist. I think that my atheist view haven't really affected my life, but religion in general has. I was raised catholic, but my family in general is divided on religion. With some catholic family, some jewish family, and one of my parents being atheist, I think that I just disliked the pressure and stress of religion and I didn't really believe the stories anyways. I decided not to get confirmed to the church (I'm so happy that I was able to choose). My beliefs did kind of just fade with time, but I feel like it was just one event after another that changed my beliefs for good. At some point we had not gone to church in a while and I prayed a bit in tough times, and nobody answered. I feel like that was the end for me.
I also think that being aromantic had a huge effect on why I became atheist too. In the catholic church, I feel like there is such a big pressure to get married in the church, and honestly, as an aromantic person, to me, getting married is not a huge sacrament that the church makes it, it is just like a legal agreement. Also, I think that parts of the church (not all, just some parts of it) invalidate LGBT communities and I just don't want to be a part of that.
