Future career help?? Jobs?? No idea how to title.

Hey, so—I wanted to ask questions about careers and the near future; I've been fearing about it for the longest time.

I'm 16, and I want to learn more about IT/ cybersecurity or psychology, but I don't know where to start. For psychology, I've downloaded a few PDFs/books onto my phone (haven't finished them yet, but Disorders of the Self, Adult Children of Emotionally Immature Parents, etc.), watched a couple of videos and documentaries, and that's about it. I'm really intrigued by disorders, improving one's mental health, how the mind works, and basically therapy work. I hate how certain disorders out there are being demonized, and I deeply care about people in general. Regardless of background.

Err.. for technology, I installed Ubuntu onto my laptop once, then switched to openSUSE, all without having any issues or a single idea what I was doing. (Well, I still have issues with it.. rebooting error). I know the basics so far and can probably name 2 or 3 terminal commands. I scored 788 on my first CompTIA test a year ago. I've already forgotten a lot since then. I blame my current living situation and moving back and forth nonstop. :(

I hate it. I feel like I haven't learned much in either area. I don't even know the right terminology to use. I crave to know more, but preferably explained in layman's terms because I have a slight learning disability. That being said, if you know anything about either field, teach me if you can. I don't know anybody in my family who's knowledgeable on either so.. I'm asking here. :) Thank you, and you're awesome!!

TLDR: I need advice on getting into IT or psychology. I don't know where to begin. Any advice will do
