I think I messed my brain up

So one day I was doing this self love thing one day (http://youtu.be/zQHv75ahYDQ) trying it out. which means asking yourself the question "what would someone who loved themselves do" for every second of the day. So, one time I thought, when I ask myself "what would someone who loved themselves do" what if that is an obsession. When I had that worry , I asked myself "what would someone who loved themselves do" and it told me to relax. So once I thought, maybe I shouldn't relax so this obsession would go away. And that's when I started resisting that, resisting the ability to ask myself that question (best I can explain it) and felt like I was pushing a part of my brain away to get this "obsession" out of me, but I was just screwing something up. So I did that a couple of minutes, and I felt something "switch" , I tried to get back to watching youtube but I had this switch and it felt weird, it didn't go away, something felt wrong. And that's when it started. about 3 weeks ago on thursday.

Everyone I told so far including my doctor thinks this is just a thought, but I think it isn't. I feel it in my brain, like the "me" is divided. My doctor put me on medication for 2 weeks and if it doesn't get better he will let me get a brain scan

Very scary and interesting. If you ask me, its your imagination, but that can be just as anxiety producing. It sounds like a very subtle form of hypochondria, and I've experienced similar things in the past; I thought I became schizophrenic, developed a brain tumor, gave myself brain damage, not to mention things that "happened" and I couldn't give a name to etc.
