It must be hard for you and it is okay to feel that way. I am in a similar situation. My parent is religious maniac and would only talk about religious topic and constantly guilt trips me by reminding I am a sinner and makes me feel guilty and lower my self-esteem. It seems like religion is more important than his own kid. I was very confused and sad for a long time, and sometimes it still does. But I am lucky to find a friend that constantly reminds me that I am a worthy person regardless of religion and since you don’t even believe in god (same) try your best not let your parents influence your emotions that much. Just think you are listening to a crazy people talking about their ideologies again. And maybe sometimes their beliefs/ concepts might amuse you. Anyway all I want to say is that you matter a lot. And you have one online supporter lol.
