Be yourself and rock it the most that you can because , in fortunately , you aren't a cat and you don't have 7 lifes, you only have 1..... so do the most of it and be happy every single day of your amazing life. And , if the things aren't going that well in your life, go to the nearest mirror, look in front , at you, and say: 'I can do this! I'm amazing! I'm beautiful! I am myself and that's the most important! I'm free, I'm me....'
And if that doesn't work, eat a chocolate and listen to One Direction, Ed Sheeran or Shawn Mendes or your favorite singer , because, I'm absolutely sure that if you can't make yourself happy , they will make you happy. 
Just don't forget this, you're amazing, I love and you love you because you are you.....
And , IF, IF, that doesn't work either , just do like Nash Grier : 'Can't see da HATERS!!!!!'
Just be you and be happy....
