How about doing some reality testing/grounding?

You're using the term "paranoia" which means you know it's an irrational fear (as long as your definition of "paranoia" insinuates the fear is unfounded). That doesn't mean the feeling it valid, my friend, but for me at least knowing there's a good chance it's not reality is comforting. But I'd say it is really good you're saying (paraphrase) "you're paranoid you're the negative energy" instead of "you are the negative energy." In a mental health sense anyways, which is what we have to keep in mind in any sort of unstable period (I know I've been gone, but I think you were struggling a bit before I left, and I KNOW you were really struggling not super long ago too).

As for your daughter going to his mom's? Eh. Kids. Unless she is genuinely terrified of you or runs for the hills at the sight/sound of you, I think you're alright in that department.

I know how much it sucks to hate being yourself. I wish I had a fix, but know you're a good person, at least from my perspective, and I know from many others' here. No way such a beautiful soul as yourself could be a negative energy
