#please i need sources so bad

hey so can anyone recommend me like a good, factual website to learn about systems? we’re doing a genius hour project and I know most of the stuff already, but I can’t exactly cite headspace as a source lol.

every time I think I find a good one it’s like “and endos exist” but won’t elaborate or anything. and if yall think endos exist bc of religion or something then I can’t say anything about that in school, but scientifically, they can’t exist.

anyway if a website says that, then it’s not a scientific, factual, website. so I need some to cite.
