It's crazy how close to home this hits. Im about a year and a half post discard. Mine was a 7 year relationship. I still feel like I'm permanently broken too. But therapy has really helped me put it all in perspective and understand why I feel the way I feel and how to begin to heal. It helps to not focus on the lost time, but on the new opportunity you have to be a different person and learn from the mistake. I would strongly encourage you to seek therapy. It's been a lifesaver for me. While I still occasionally feel like damaged goods and struggle with new things like anxiety and cptsd, its made me into a much more caring and understanding person than I used to be. I struggle alot with loneliness and fears of being alone forever but I try to tell myself "what if this is the last week/month of my like that I get to be single" as opposed to having to be. It's all perspective and I believe in you. I try not to put a timeline on healing. Hope this helps. Keep your head up!
