Confused

This isn’t really a secret though . It’s just something that has been bothering me about myself .
I am a very sweet , loving , peaceful and caring (based on general observations) lady but whenever I am angry , pissed , hurt or insecure I become the opposite of sweet , loving and peaceful .
But it always simmers after a while , like few minutes and I begin to feel bad about my personality switch.
I know it’s probably not a normal behavior but what I wanna know is , is it just me that has this kind of personality or behavior and I have been really trying to fight it but I don’t know how to .
Can anyone love like this?
