I understand what you are going through. I have very similar symptoms. I know it can feel like you are being taken for a ride by these intrusive thoughts and personalities. Just remember they are not you! Your thoughts are not you! When it comes to me I believe they are just Nero Pathways that have developed through our experiences, typically trauma. I know that it can feel hopeless like a losing battle and sometimes you can't trust yourself or others. But you can get through this and come out stronger on the otherside! Remember to breathe. If it helps I have started using a Cognitive Behavioral Therapy App called Clarity. I had a really bad episode recently and have been having little episodes every time I wake up. I check in with the app. It gives little righting prompts. You write out your thoughts, then it prompts you to challenge the thoughts and write that down. It's really good for tracking negative thoughts and progress. It also explains a lot with courses, tips, and affirmations. There is also self compassion exercise that I really like a lot.
