I know this is counterintuitive but this really sounds like a candida, parasites and heavy metal toxicity problem. I know because I used to have the same exact feelings and they didn't go away until I addressed these issues and did an intensive detox, then I stopped caring about stupid things and just had a feeling of bliss almost all the time. You see these toxins are causing all kinds of obsessive negative thoughts in your brain and you feel like it's you but it's not you it's these opportunistic organisms living inside you that are making you crazy
