gf gets really angry ? advice pls

hi everyone, first time posting here, me n my gf have been together for 5 yrs, she has very concerning bouts of um… i guess anger? i’m not sure what to call it…. but when she gets angry she really gets angry, breaks things (sometimes, not always) throws things (again, this is depending on how angry she is) like the closest thing to her, the most recent thing she’s thrown (n broken) was a ps5 controller, she threw it with such force and anger it broke. she hasn’t hit me though, never. although sometimes she can be um, verbally abusive when we have heated fights, not sure if those are the right words… how do i proceed? any advice pls? thanks guys <3 it’s kinda scary when it happens :/
