Hi everyone, so this all started around 2 weeks ago, when I had a crazy thought. Ever since then i've been freaking out about it. I've always been obsessive, and has anxiety, but never this bad. I had a sexual thought about a coworker while looking at my boyfriend. It was horrible, and it was unwanted. All day I had been stressed out about something that happened at work, and this popped into my brain. I can't stress enough how much I didn't want the thought, and now I'm scared i'll never get over it. What if I think about this co worker during sex? not because I want too, but because I'm scared of the thought. I don't want to have these thoughts and I don't know why now it just happened, like I don't understand. I am in love with my boyfriend, and I never had any thoughts like this before, so why now? Will this ever go away? I feel so horrible, do I need therapy? I am seriously more scared of thinking about the thought, or having the thought, then the actual thought, if that makes sense. I don't know how to get over this. Is this OCD? It's just one specific thought, and fear so I don't know if its OCD or not, i've been stressed, and I know stress can trigger it, but I don't know. I need help, I don't feel like myself, its all I think about, I feel trapped in my head, I wish it would have never happened. I want to note that I am not trying to "suppress" feelings for my co worker. He is a nice looking person, but I would never ever leave my boyfriend for this person, nor did I ever want too. A month ago my boyfriend and I broke up over something stupid I did, and I hurt him badly. Now I've been obsessing over things I could do that would hurt him, and make him break up with me again. We are back together but I am REALLY messed up. I feel like a horrible person, and I compulsively confess everything to him even if they don't matter. I think this is a reason the thought happened. I was so obsessed with what happened at work, that this co worker was on my mind, and my brain new if I thought something like that, it would make him upset. It's like my brain was trying to punish me. Does that make sense? This bad anxiety all started after he broke up with me. It's really messed me up, and triggered these thoughts. I don't eat anymore, or sleep without feeling like a horrible person. Could this explain my bad thoughts? How do I get over this? Will this be my life forever? :( I never felt like this before the break up. I try to let the thoughts pass and not give them any attention but I don't want them there. It causes me anxiety and makes me angry that my brain is aware of this now. I just don't get why it's happening and why I can't stop thinking about it.
