That's what happened with my second discard. Although it was about 2 weeks good, and then one week kinda, with one week detaching. It hurts. Especially because I felt like I had gained my passion for life back (I don't know if you did either).
And that's okay to feel confused and hurt. It means you are a human being who cared/cares about someone else

There's nothing wrong with what you are feeling. It might help to try and identify what it is you are feeling. I know that's hard sometimes. Because like you said you have been hit by a train. I know I felt completely lost, sad, dejected, angry, resentful, guilty. All of it just came out of nowhere and came and went.
But those feelings are okay. There's nothing wrong with feeling. In time this is all going to reveal itself to you.
And thank you for the words but I'm not a god send

I read your post and know exactly what it feels like. As I said, I'm still going through it. But you're a caring human being who is hurt. And you deserve to be able to share and talk to someone right now.
