I understand how you feel OP, like yourself, I'm very disappointed they decided to pack it in and move on.
That said, WOTC are not easy to work with, they have a reputation for being douchebags and it's one they've earned, there's no doubt in my mind that they were being pushy towards Larian regardless of what Swen has said, they almost certainly wanted to capitalize on the success in the same way EA did with Dragon Age Origins, which resulted in a rushed out game in DA2. I feel that Larian couldn't be bothered with poking and proding and just called it a day on Baldurs Gate.
And I'm sorry to hear about the difficult time in your life, I truly hope it does improve for you, but for me BG3 wasn't a good game because it was DND, it was a good game because Larian made it, try giving Divinity Original Sin 2 a try. As long as their next game isn't something like fallen heroes which sounds basically like XCOM meets Divinity then I'll be buying their next game.
