Hi and welcome, that_girl! I'm also a never-jw with some friends and family "in".
My experience has a lot in common with yours. My ex-SIL and I were good friends and I tried to keep the relationship going after she and my brother seperated. At first I got letters with a page of family stuff and 2 pages of preaching (emails were too dangerous to her), then when I began to rebut the preaching, she sent the local jws to call on me.
So began a so-called "Bible study"; again we made no headway. The beliefs were just extreme and no way would I follow the ridiculous question and answer method. After a few months we gave up, and since then, not a word from ex-SIL, although I wrote twice more.
About a year ago the "study" watchtower had an outrageous article about "apostates", calling them mentally diseased, and since then the pressure has continued to keep the faithful afraid of the world and its satanic influence. Your poor friend and her mother are indoctrinated, I'm afraid.
And congrats on your psychology major!
Keep posting and reading; you'll learn a lot about jws here!
All the best, Retro
