The thing is everyone will tell you different things, and of course, different things help different people.
As you've asked, I can tell you that EMDR therapy helped me and proved to be a real turning point. I got mine through the NHS eventually, after talking therapies and CBT hadn't helped.
I ricocheted between immense anger, shock, betrayal and trauma for around 3 years. It was like being trapped inside something and I couldn't get outside of it.
People telling me to move on, not to be bitter etc made me feel worse.
I did all sorts of positive things to help myself - they did help, but I kept circling back and ruminating.
Amazing friends, emdr and time were what got me through.
Two years isn't so long really. People who haven't been through it don't get it. Be kind to yourself. You will get there. X
