It doesn't sound insane at all. Especially since you're questioning your sanity. You're not giving excuses. Your learning about yourself and your parts. I hear voices. There is a hearing voices network website and some interesting YouTube videos to watch. You may find, as I did, that you relate to some aspects of the different people. This helped me feel not so alone in my thinking. Questioning your parts and talking to them is helpful. Don't be afraid of them, is my advice. They only live in our worlds. They are real to us. Like God, others have the right to believe in something not tangible.
