Sure, you may be going through a lot right now. Things may be bad at home, friendships might be taking a bad turn for you and everything you do may just stress you out.  At such times, anything anyone says to calm you down may just end up triggering you more. You yell out offensive things and have no control over yourself. You hit your best friend. You break whatever you get your hand on. You feel better just for the time being by doing so. You cannot think rationally because your temper has got full control over you.
You isolate yourself from everyone around you for some time. Your friends are pissed at you for yelling at them when they tried to help you. When they tried to be there for you, you ignored them. Your ego doesn't let you apologize to your dad for your behaviour. You are all alone.
Sure, this won't last forever. Your friends and family will finally understand that you just lost your temper and said things you didn't mean. They love you enough to understand you. Or is it that they have lost hopes on you? Must be the latter!
You are so full of yourself that you don't realise the weight of your words. What about their feelings? They are not obliged to forgive you everytime you lose your mind, remember that. One day, they won't and you'll know what being alone feels like. Instead of being a jerk and believing that they will always understand and come back to you, take steps to control your temper. You may have apologised for what you said but the things you say may haunt them for several nights. You may have apologised for raising your hand on them but the scars may hurt even after they disappear. You can't control how someone feels about these things, but it's in your hands to not let them happen.
Spread kindness always, before you realise it's importance the hard way. It'll make the world a better place. :)
