Hold on to your dreams. Hold on to yourself. If there is no one, there is still someone. You. You will always be the only one who is there at any time. So treat yourself well, you deserve it. Live your life always to the fullest, because you only live once and never know when it could end. Do everythimg that makes you happy. Never give up on your dreams and if someone says to you: ,,You can't do this or you can't do that", just tell them: ,,Oh really?? Watch me" 
I know you can do this!!

Love u always :)
