Sirius POV
It had been months since that day. I was slowly getting weaker and sicker. But I'd done what he asked me. I'd left him alone. For the most part, he looked happy. He no longer even glanced at me. It hurt to see him so happy with others. He was my mate.
The last few months without him had been terrible. I no longer slept. I could not sleep even for a few minutes before I either had a nightmare or woke in pain. I was in pain all of the time. I constantly felt like hot knives were slashing at my body. All the time. Sometimes it was all I could do not to cry out. I bit my lip with the constant pain, which did nothing but allow me the taste of my own blood when I longed for anothers. Remus' blood for that matter. He was my mate and I still had not tasted his blood.
My vampire was angry at first. Angry at Remus for refusing us, for telling us to leave him alone. Then angry at me for making him feel that way. Then he got sad. Sad he couldn't touch, feel or taste our mate. Then he slowly got sicker and weaker, just like I myself did. Soon it took all my effort to get out of bed and dressed. I was getting slower.
I could see my brother Regulus and the other slytherins giving me confused or worried looks, not to mention my teachers. I waved off their concerns and claimed tiredness. But Regulus wasn't fooled. He knew Remus was my mate. He also knew what happened if a vampire did not mate with their intended. I had been avoiding talking to Regulus for a while, afraid of what he'd say. I wasn't stupid, I knew the consequences of Remus' actions. But he didn't understand why I wouldn't push Remus. Due to this, Regulus stepped up his teasing, pranking and fighting with James Potter and his friends.
It was a drizzly Tuesday morning that it happened. I had left the Great Hall early, due to my lack of appetite. I had not eaten anything, only drank a cup of tea. I was walking up the stairs to Transfiguration when suddenly I went dizzy. I closed my eyes and went to reach for the handrail but I couldn't grasp it. Suddenly I was falling. I was too weak to even cry out and I just closed my eyes as I felt the easiness of falling against my slowly numbing body. Then I hit the floor and the blackness was a welcoming distraction.
