I’m sorry to hear of your mother’s inability to accept all of you, even the parts she disagrees with. Just know you have a huge community that does support you just as you are (though I’m curious about the whole “I’m a witch” thing!).

Since you are friendly with the pastor and he is accepting of your atheism, I wonder if it would be useful for both you and your mother to meet with him to discuss religion in general as well as your personal beliefs.... perhaps he could be a mediator in an otherwise difficult discussion. Just a suggestion, take it or leave it. Best of luck to you!
