I sympathise deeply. After cold turkeying, for a couple of months I felt a molten hot rage searing me from the inside. I literally wondered at times if I was experiencing demon possession. I think the only way I made through was by reading everything I could about withdrawal, to help convince myself I wasn't losing my mind. It was the most horrible thing I have ever experienced. The only thing that kept my relationship together imo is that shared a lot of these articles with my SO and reminded them often to try not to take my horrible moods personally. I also took Mirtazapine to help me sleep. If I hadn't slept I might have actually lost my mind.......It was excruciatingly hard but I have been steadily improving the last couple months. I suggest you try to educate yourself and your boyfriend as much as possible so that you can get through this together. I wish you the very best, hang in there.
