I’m very sorry you’re going through this. Someone broke things off with me and it still hurts, even if it has been a while. The first month was the hardest, then it gets easier bit by bit. What helped me was keeping busy with work, I had a lot going on to keep me distracted. I tried to do things that I didn’t do before, or that I wanted to try and never got the chance to do, or stopped doing when I got in the relationship. I found it important to try to enjoy my solitude, but that takes time. Go places, even if it’s very near you. I delved into my hobbies to keep my mind off of it. If you can, try to process things bit by bit, just don’t try to escape your feelings in the long run, that fucked me over(It’s been a while since I avoided processing my former relationship so yea).
