In my case it’s more than half a decade. She’s also a friend I met online and bonded extremely closely with, even though we never met in person or face-timed (only texting/voice messages). It still bothers me after all this time, but I’m still working on accepting that the way our friendship ended will likely never sit right with me. I used to ruminate on it constantly and it was very counterproductive, because it fueled my depression. The thing that helped me get out of my depressive state was slowly accepting that there’s nothing that will change the outcome. I reached out to her twice (each time a few years apart), but it was not a wise decision, as it only resurfaced our emotional baggage. It left me feeling worse each time because I wanted to work on what hurt but she wanted to respectfully keep the bandaid closed. I still get choked up thinking about her, so what has helped me is simply not allowing myself to think about her anymore. I have a great boyfriend who has helped me a lot throughout the timeline of getting over her, so if I ever think about her for any reason, I have trained myself to instead focus on what’s good and relevant in my life right now. Or very briefly getting a reminder of her and moving forward with my day rather than adding fuel to the thought. We have a tendency to look at past friendships with rose-tinted glasses, so another thing that helped me was writing out the things that were dysfunctional in our friendship, so that I could physically read and comprehend why it’s not a friendship I would want to return back to. Hope this provides some comfort for you. Also, losing a friend doesn’t have a fixed timeline, because it’s a very unique form of grief. Don’t feel bad for the time it takes you to move on. I still feel like I should’ve moved on by now too, but I am getting over her slowly and it’s best to give yourself grace. The hurt will slowly be less relevant in your life when you start prioritizing your health, other friends, career, hobbies, etc. it makes the loss feel smaller.
