I think I'm being ghosted by a really good friend, and that's my biggest fear. I've lost so many people in my life that way. My best friend in high school told me that I "know what I did" and then cut off contact with me. For the life of me, I can't think of anything that I could have done to her that could possibly be taken the wrong way, so that's been eating at the back of my mind for years now. Other than her, I've also lost another close friend shortly after we slept together - I think that she must have had a bad time and didn't want to face me again. Those two hit the hardest, but they're not the only ones.
I just don't know what to do anymore. Every one of my closest friends has left me so suddenly and without explanation. I've come to expect it.
