Vent possibly? I need advice

Last night I was at my support group (for context, I've been struggling with mental health and really just keeping relationships) and I know this person named Ezekiel, and both me and my partner are friends with them, I haven't talked to them in a while and honestly, I was just In a really horrible mood because I had almost gone to the hospital like 2 hours prior. I didn't want to talk to anyone, so I ignored almost everyone, Including Ezekiel, and I think he thought he did something wrong because I found him crying. So I tried to apologize and tell him what was going on and he responded with "Well, you usually talk to me.", and I just went to the bathroom and started crying. My boyfriend found me and we sat together and he was just like "Ugh, I hate being in a trio", and me and him decided that I should apologize to Ezekiel. So I went to apologize to Ezekiel, and he responded with "It's fine", which at the moment felt extremely un-sincere because I was genuinely apologizing and I went back to my boyfriend and started talking about it and he just ran away and I was like oh shit what did I do. I found him crying in another room and I just freaked out and ran to the bathroom and screamed, like I screamed like someone was hurting me, because I thought I had hurt him. And one of the adults calmed me down and I eventually talked to my boyfriend about it but he was like, "Well, you could've stayed in the room with me when I was crying, you didn't have to scream because it felt like you were trying to take attention away from me". DUDE, I was so fucking overwhelmed in the moment and I had no option or way to get out my emotions without screaming, which was wrong of me but still. I haven't talked to him since yesterday and I don't know what to say to him now. I desperately need advice so if you guys have any PLS GIVE.
