Hi, the answers here are really strange to me because I am going through the same scenario. My son acts like I don't know him and never did. He calls me shameful names, tells me to bury myself in possessions and that I am a lying pig, a lying pig?? He broke into my house and broke the external windows. The month before, I had to call the cops so he would stop harassing me in my own home. He moved out. This month, I had to pick him so so he could use my car and he freaked out saying I was 15 minutes late. I wasn't. He said that I apologized for being late the next day. I didn't. He freaked out and it's come to this.
The reason why I say that your answers are strange is that your sons are 18. Mine is 23. Does this mean he's a late bloomer or that he is psychotic for sure? I'm really serious. It's very scary. We don't talk to each other at all... mainly because he hasn't made one attempt to do so and because I am way too shocked to even attempt to.
I think the advice here is correct: Let them be. No contact is the best. I can honestly say that I don't miss him... I'm too shocked to feel anything. I just hope he comes out of this soon. It's really sad because before this, we were very, very close. Perhaps that is the problem. Nevertheless, I have no guilt about this at all. I'm done with guilt. I'm a good person who just happened to be surrounded by a sick family and I'm just becoming able to pull myself out of it. Me thinks that I am alone in my survivorhood. Take care all...
