Got kicked out from my friend group without able to explain

I thought one person in it was my best friend; I was the one who checked on them every day, stayed up all night during their breakups, gave advice, sent memes when life sucked, even gave them my driver’s-license flashcards. Last week it felt like a completely normal Discord night. I’d just come home from urgent care with a bad coughing infection and was on three different meds that made me foggy. I didn’t reply for a few minutes in the call, and later I made one dumb joke about “tortilla with cilantro” (blanked on their diabetes for a second). That was it. No “hey, that hurt,” no chance to talk. Just an immediate wall of text calling me a bully, saying I ignore people on purpose and think it’s “cute” to hurt them. I sent apologies trying to explain; they blocked me before the messages even showed as read. Whole group followed. Looking back, I think they’d been wanting me gone for a while and this was just the excuse. But also there’s things that this individual may do that I feel uncomfortable and also this individual the things I felt like more normal but I didn’t question it since I didn’t wanna leave the friendship. Same year my girlfriend of four years left me, so I’m basically back to zero people again. Been bed-rotting a lot this week, but the weird part? I also feel… relieved. No more walking on eggshells, no more 3 a.m. crisis calls, no more being scared to say the wrong thing because they “trigger easily.” I wish we could’ve had one real conversation instead of a drive-by execution, but it is what it is. Honestly, I hope this person doesn’t hate me every day. I feel like they do honestly I thought it was just a normal discord night. I just hope they have a happy life and i’ll make sure I learn from this experiment and make myself into a better
