Need advice on dealing with religious family pressure

I was raised LDS and still am but I have a lot of friends who have left our church and I care for them just the same. To be short and to the point I would sit down and ask your mom to talk. Use phrases like “I feel ___ when ____” and “In the future could you please ____”. “Is there a compromise we can come to while I’m still living at home”. I’m a teacher and we use a lot of “I statements” in conflict resolution because it helps point blame away from anyone and hopefully helps the two people listen and understand each other’s feelings. Hopefully if it is a calm conversation based around feelings, your mom will listen.

I understand completely. I was raised LDS. I was forced to attend similar events as a teen. I have spent time since trying to figure out where I feel the most welcome. I found that I don't belong part of organized religion. My faith and my beliefs are my business

I was raised Catholic. Eventually, when I was around 19, I put my foot down and stopped attending church. I tolerated it through my teen years because I was still living under their roof. As an adult, I found that reasoning with them didn't work and a simple "no" was the most effective method for me to create distance. I am 29 now and staunchly refuse to participate in their religion and still haven't told my parents I'm an atheist. 😆 At some point you have to put your needs ahead of their feelings if they won't be reasonable, especially since you are an adult.

Not sure how much this might help but Johnny Harris has a great video on all sorts of those issues on a video called Why I Left. It's on YouTube. At the very least maybe it could help you feel less alone in your situation. All the best!
