What would you call this?

She used to be my best friend and we lived together for 2 years. She was obviously really depressed and so was I. It maybe happened 3 times where in the middle of the night (almost positive she was drunk) she started breaking everything. It was only the last time tho I could hear her crying really loud and she said she didn’t wanna live anymore. At the time I remember I used to be scared and didn’t know what to do. What would you call this? Manic episodes? What could have I done to help her? It’s been in my head for a week and I dont know what to think of it.
