What could I have done better here? Is my betting off?

It's interesting to know what you're though process was during the hand,
Pre-flop I don't defend so wide with a suited 1 capper without position.
Not sure about those over bets against 2 unknowns, but if both villains are passive I would most likely Cbet flop even 2 times pot with the intention to shove the turn. Normally I would check/raise flop and re-evaluete on further action against the BTN open.

Well, looks like what you really need to do with you game is to find some basic charts here on pokerstrategy or explore GTO Wizard, because calling 53s on SB to any sizing is way off, especially vs unks (unless maybe you have some revolutionary ideas or intuitions, which I dont discard, cause game is constantly evolving). By the way, calling J8o on BB is way off too, especially when SB also called.

Snap fold preflop. As played I would check flop as my perceived range from SB should hit flop very rarely. We can either x-c or x-r versus bet though x-r is most likely preferred play. From BB I would like this lead.

I agree that I should've folded. I've been liking to play suited one gappers because it's very hard do identify those straights and I get payed off so often. My thought process besides that was that I was over betting the pot in order to not give pot odds to the vilain but it apparently didn't matter here since I got called every street and vilain made their hand anyway ... besides not folding on the flop I think it's weird I got called but yeah...I should've folded.

Thank you for all of your insights. I'll be folding this from now on ... I hope!
