n me this is called mood swings, in an older relative this is called menopase, in another relative this is called schizophrenia,

my point is it can be many things and only your own treatment providers can tell you what this is in you. if this is about someone else only their treatment provider can answer what this is inside them.

my suggestion is if this continues to bother you contact your treatment providers who can tell you what this is in you (in other words make a diagnosis and get you treated for it.)
