Sorry for the late reply !!! But, here is some good websites to learn:
https://www.simplypsychology.org/ : this one is really easy to understand and has many situations for u to learn, or how certain things work. Its really easy to learn. tho this is like the only website I know other than the book websites. but also you can watch some YouTube videos or psychoanalyze films. But it really depends on which path u wanna go in psychology.
also there are some websites to read books for free. I can give u some other websites to read anatomy books if u want :D
Psychology books & websites :
OpenStax - here is like the official medical books and like the main source for these. tho they are more boring (if u aren't used to reading a lot) but much more professional and will help u if u want to have this career in a future.
There are two main books in OpenStax that are the Introduction to Psychology, and Psychology 2e, or Anatomy and Psychology 2e. Those will help u a lot !!!
There is also LibreTexts and Open Text Book library, but sometimes it will show u the same books that are in OpenStax, but there is also other books you might wanna look for cuz they dig in some more specific disorders. And if u did visit those sites then, u maybe should get into dual enrollment classes if ur university or high school has them, just to down the future debt a bit. But yeah that's all I can give u !!! Hope it helps :))
Also,,, there are more advanced books on those websites (I just read that u aren't really new to psychology, SRRY FOR NOT READING ToT)
