Realize that time is like a river. During your life you'll be tested with waterfalls, rapids, rocks, and sometimes still quiet waters.
Find outlets for your emotions first, and then find a reason to keep going
You are just at a bad age it will pass ,just give it a few years. Life is full of great things ,especially your Life. :)
Do what makes you happy
Decide that that's what you want to do and pretend you feel happy and want to go on until you realize that you're not pretending anymore.
