Obsessively Aware, Please help!

Hello, I have been struggling with a spike in my OCD this past month and it has been very debilitating. My OCD centers around a certain violent thought that I have and while I have been able to get over it for the most part, it is always there in the background and I know that this is where my compulsions stem from. In the past few months I have been getting better at desensitizing myself from the thought and have been even confronting some of my compulsions.
Last month however, I had a situation that caused an immediate return of my OCD in full force. After finishing dinner one night, I wanted to finish the salad that was leftover. My mind told me "No, do not eat that or you will be doomed." Silly I know, but for those of us with OCD this is a real problem. I felt strong and I said "I want it so I'm going to have it, screw you OCD." Immediately after doing that my mind was taken over by the thought and I could not get rid of it. I woke up the next morning and it was still there which eventually led to weeks. I had practiced strategies I had used in the past to get rid of the thought, but this only led to mild success. The real problem came from when my OCD began to take on a new form altogether. I began to obsessively think about my thinking! It sounds crazy, but I seem to have become stuck in this pattern of "watching" everything I do. For instance, if I am talking to my mom my mind says "You are talking to mom." or if I am eating I make a mental note that I am eating. This happens 24/7 from the time I wake up. I have even begun this inner battle with myself over weather I am a good person or not and sometimes the thoughts that tell me I am not seem to win and it doesn't feel like a thought it feels like it's me. This thinking does not stop all day long I can't read or watch tv without having this going on at the same time. Since the my mind is obsessed with itself it is hard to get over as it is all internal and has to do with me. I don't know how to break this pattern as I have gotten myself into this habit from the minute I wake up for the past month. Has anyone here had a similar experience or any suggestions on how to get out of this? Please help!
