You couldn’t be more wrong, I do care!
You’ve got guts, kid! At least you tried it! And you didnt even say youd never try it again!!! That counts for a lot. When I first tried it, I had the exact same feelings you did.
I think you are on the right path 
You identified that you need to learn more first, and there is ZERO shame in that- This is a complex game where build mechanics are concerned.
Experiment with the classes, find some combos you like. Maybe dont go Hardcore yet at all. I started Softcore until I had 40 characters, but still only 2 or 3 that hit level 100. I enjoy whats known as “meme builds”, which are basically janky builds that have something really cool that they can do but are pretty much useless outside of that thing, whether that means their damage output is abysmal (Old school Battlemage) or they are toast if someone breathes on them at the wrong time (max Dodge/Evade), meme builds are not well rounded, but they are fun, exciting, and most of all unique!
I wanted to be able to play in a way that captured that uniqueness, while conforming to some type of meta via min-maxing stats as little as possible. The answer for me (simply because the majority of players don’t do this) was to play Hardcore Classless, and was inspired by a deep character creation process that @MikeHeydon cultivated in his personal NPC and LORE based thread. I highly recommend reading this thread if you are looking for inspiration before you attempt Hardcore Classless again!
Regardless, welcome to the community! I should have opened with that. You’re officially one of us in my book now that you’ve tried and died!
