God a year of this pain I just cannot do it
To be blunt, how are you going to not do it? How does that go?
If you think back a month or two, you'll remember that you didn't even want to feel better: you felt like crap, but recovering would have felt like an insult to him, to your relationship. It would have felt like 'letting go', and you didn't want to.
Now, you just want it all over, you're ready, to the point of frustration, to move on.
Recognise this as progress. I'm sure that, to start with, you had a spell where you didn't even accept that it was true, right? Let alone want to get over it. You're on a journey. It has lots of steps that hurt, but you've done lots of them already. You're moving forwards. You're not 'stuck'.
Posts that say 'It takes x time' are pointless. It takes as long as it takes for you, with your experiences and your personality, after your relationship and your break up^. Nobody can tell you. But if you're utterly fed up with being miserable, you're closer to the end of miserable than you think. We all recover, once we're sick of being not recovered.
