How can i control my anger and not take it out on others?

There has been times where im Mad and i sometimes take it out on other People, also when my friend and i make plans to go out and have fun Something Always happens that messes it up and as a Result i get Mad and take it out on other people. Also i think it might be cause when am afraid that i might not get another chance to do something ive always wanted to accomplish and cause sometimes i feel like its too late for me to fix my life and i dont seem like am angry but since all my friends and Cousins have a better Social life then me, it makes me feel bad that i dont have wat they have, and on the inside i have alot of rage and anger inside
