2 years ago I was still smoking shard (ice/meth) & which I had been doing for a period of 3 years with my partner. I began to become extraordinarily jealous & suspicious of him. I once found some fairly innocent messages between him & an ex of his & completely lost my ****. I went blank & feel as if it hurt so much I may have even been dissociating, I remember just feeling numb & staring & my partner being really upset & trying to get me to speak but I couldn't. Total overreaction. I then started to stalk his facebook & email & phone & was not shy about it. I felt I was in the right. I would listen to no one when they said I was being crazy about it. I would spend hours searching for evidence. Literally sometimes even a couple days when we were actively smoking. It consumed me. I would get into a state where I couldn't talk to the people around me & instead obsessively searched for evidence of his "cheating." At the time cheating also meant looking up porn to me. I don't see it like that anymore. It was as if my extreme jealously & suspicion faded slowly but significantly after I stopped using. I was at the point that I was installing key logger software on his computer I was so convinced of his cheating with absolutely no proof that wasn't based on some theory of mine about what he was up to. I have since been given a bipolar spectrum, probably bipolar 2 dx. Has anyone else ever experienced this? I presume it was related to the drug use but I'm just curious as if you read about morbid jealousy or delusions of infidelity I can pretty much tick every symptom box during that 3 year period.
