Everyone gets angry but if you're concerned then it must be a problem. Feel free to contact me for short term medicine as well as anger management techniques.  Will also have to see underlying reason for anger. 

Hi Sit calm and find out what's the causes (trigger) for your sadness or unknown fear. Once you find causes it's easy give suggest recommendations. There is also chance of hormonal changes. Your daily activities should not affected by your stress factor for more than 2 months. If so pls consult a psychologist for further help.
