experienced some sort of psychotic episode last night and ruined my relationship, any advice?

the worst case scenario of anything ever happened yesterday, i was tripping on lsd with my at-the-time girlfriend, slightly more than i'm used to but not a particularly strong amount, when something went wrong and a switch flipped in my head and i completely lost touch with reality. i almost fully blacked out and was told afterwards by her that i had torn up the flat and smashed a window because i was convinced we were both dying and needed to escape, that i had (for some reason) tried to rip her septum ring from her face, and that i had escaped the flat and she couldn't find me and had to contact campus security and emergency services to locate me. from the sounds of things she told me she found out after finding me with security and paramedics and the very few things i remember, i had been fully delirious and disconnected and that i had said i was taking things i had never touched and was speaking fully in gibberish, and that i was convinced i was dying and replaying my last moments over and over again. i ended up in a&e and today she called to say she doesn't feel safe around me and she doesn't want to be in a relationship with me anymore, nor does she want to be around me in person at all until she feels she can trust me. i don't blame her whatsoever but... holy fuck, how could something like this happen? i've never been a violent person in any manner, i don't have anger issues or anything like that, i have a distant family history of schizophrenia but i never imagined an episode like this could happen to me. i feel almost traumatised by the events and the hallucinations and delusions i was experiencing. i don't understand how an episode like this could completely lose control either. but more than anything i feel extremely guilty for the things i did, i've never wanted any harm to come to her or anyone really and now i feel absolutely awful. i just needed to get this off my chest, i don't know if anyone here has been in a similar situation but if anyone could offer any advice i'd really appreciate it
