My recommendation would be to talk to your GP ASAP regarding issues relating to your anger or other emotional problems. Alternatively, contact the Samaritans or other helpline. Sometimes it helps just to have someone there to listen without judgement.
You are never alone. Reach out and talk to someone if you are feeling out of control. Anger is a difficult emotion to control, but generally is a symptom of other forms of distress. Letting it control you will only make things worse. Seeking advice or a listening ear in this situation could prove helpful, and you've nothing to lose by giving it a go!
Best of luck!
