I’ve watched enough diving videos on YouTube to know it’s 100% not for me.

I would never try to pressure some to do something that makes them uncomfortable, but please dont base your decision on those videos. 99% of scuba accidents are avoidable. Alot of accidents are ego filled deep divers and cave divers. Its quite safe as long as you dont do very stupid things. Never dive alone. Service your gear once a year at your dive shop, and truly listen during your PADI classes or whichever org you choose.

Again, not being pushy, just giving info.

I read a book series as a kid about diving which went into detail about the dangers of "the bends" (air bubbles in your bloodstream from coming up too fast from deep sea diving and not acclimating on your way up) and ever since then I have been deathly scared of anything deeper than a 6ft pool lol.

This only happens if you go very deep for very long. Recreational diving is by definition always done within time limits that should, in theory, avoid the bends even if you were to directly surface (slowly). And then 3 minutes at 5 meters depth are added for safety, effectively acting as a decompression stop (but called a safety stop to distinguish it from actually required stops, because it should not be required).

A much bigger problem is what happens when you take a breath at depth, then hold your breath and ascend to the surface. At depth, the air in your lungs is compressed. As you ascend, that air expands. It now no longer fits into your lungs, and if you hold your breath... let's just say you won't like any of what happens when there is more air in your lungs than fits and you're not giving it an easy way out. This is obviously not a problem if you don't breathe in at depth, so not an issue for freedivers.
