Argued With A Friend

my best friend went through some terrible shit recently, but she never told me. so, the night it happened, i was upset over nothing like always, so i complained about a headache with her. probably because of the problems she had, she told me that i complain too much and i should stop because she can’t do anything about it. for whatever reason, i was upset like hell. my mom did the same thing and i ended up crying, but anyway. then similar things happened until a day later she refused to talk to me. when i asked her what i did do i could apologize, she started repeating a bunch of things and things i did that bothered her but she never told me about. i ended up crying real bad because i felt betrayed because of my low self-confidence. something like this happened in the past with another friend and now i ask if i’m bothering someone a lot. she’d always respond with no and reassure me, but that day i realized she just internalized everything that i did that bothered her. i wish she told me so i could’ve stopped sooner, my mother even did that for me. in the end i told her i was sorry with a giant paragraph about why i was sorry ans what i was sorry for, and she ended up listing more things about me. in the end i announced to all my friends that i was taking a break, but i didn’t tell them it was because every hour she said more and more. it hurt a lot. anyway, just wanted to say this, sorry if it bothers anyone!! no need to answer, i wasn’t looking for one to begin with. thanks if you read this, but you spent time you can never get back lol. now, sorry for using your phone area as a rant booth! toodles :)

Me and my friend have been together for like 5 years now. Today, I made a joke and they took it as an insult. I think I hurt them with it and I really want to apologise (I already did once but I feel like it might not be sincere enough or they just ignored it). I dont know if I can let our relationship just die like that because I really don't know what to do espically if our group will have to split up because of it. Please give me some advice ╥﹏╥
