Is this a mental condition?

hi I just want to know about a thing, so my friend has some real anger issues sometimes and she argues a lot but whats strange and annoying is that when she does argue she literally never stops like even if you give up and shut up she goes on and on about the same thing for a long time even if I am away enough to not talk to I still see her muttering

I just want to know if this is linked to some kind of mental condition because
I find that kind of behavior strange and peculiar

Not everyone with bad behavior Issues including anger has mental Issues. Anger is a perfectly natural human emotion, some express it more than others. Even people with worse case situations dealing with anger don't have to have mental Issues. They can have all sorts of reasons why anger is present that has nothing to do with their mental state of mind. So the answer to your question is NO. Putting labels on every emotion/and behavior is not logical or rational, and although I do realize there is a lot of mental Illness in the world- too often people try and put labels on behavior so they can think they have an understanding of this person and why they do what they do. Unless you know a person really well ( I mean spent time with them day in and day out in the real world ) you will never totally understand why they do what they do, how they think or what drives them emotionally.

I have a relative that does this and they do not have any Mental Health issues . I agree with HLP -
sometimes people behave in ways that seem odd to us , but that doesn't mean they have anything that can ( or needs to be ) "diagnosed" .

My relative goes on and on and on when they are upset . The topic can last for hours or even days depending on how strongly it affected them . It's hard to be around them sometimes , but I love this person and I accept that this is the way they are and how they deal with their emotions .

thank you, this really helped a lot the reason I thought this kind of behaviour was strange
because it is totally new to me and I have never seen a person act like this so i was just curious glad to know she is alright
