Dear x,
You know I would do anything for you right? You have helped me, I have helped you, and now it's my turn to help you, so as long as I'm around I will do everything I can to make sure you do not give up whether you like it or not, got it? I will not sit here and watch you destroy yourself, I will do anything and everything I can for you, I will always be there for you through your thick and thin no matter what, all I need you to do in return is to keep trying, I know you can do it, you have done it before, so let's try again, okay? And please, promise me that you will eventually live the life you have always wanted, be happy instead of sad, laugh instead of cry, and smile instead of frowning, be strong for me, can you do that for me?
