Fudged dice ruin the mood for me. If I’m playing, I’m there to figure out how to make crazy things work in spite of the risks. If I can’t have that, I’d rather just read a book.
I don’t usually talk about it in the middle though - I believe arguments at the table should be reserved for serious conflicts (rudeness between players and so on), not personal preferences. This is more a reason I’d check out of a campaign gracefully, and it’s also one of a hundred reasons I really prefer to GM instead of play.
Another voice here to tell you that there’s hope. I felt like you after high school too, but I found my way eventually. Hang in there. Keep reaching out for help when you need it. Things absolutely can be okay, and more people want to support you than you’d expect.
