That i get the urge to kill

Well, it all started with my mother when I was just a kid. She would tell me not to date any girls because they were bad people and that they just cause troubles in your life and that as you get older you realize love is something you don't want. So as I grew older I've met these girls in my life that I soon developed these certain feelings that were rather undesired for me, remembering what my mother has told me I would push these girls away. which would cause me to go into depression so bad that I would get these sharp pains in my chest. But as I grew older I learned to ignore my sad feelings, of course it was a bad idea to ignoring these types of feelings. But I couldn't stand these feelings, as time passed by I started to develop another feeling... Anger. Now I get these feelings at random times were I get angry but I mean REALLY angry ( Like Hulk Smash Angry). I just feel like killing someone because I think if I just kill someone then I might feel better and refreshed.

So my question is it normal to get randomly angry and get the urge to kill someone?(Just thought I'll add my story for people who LOVE details)
