Happy days die...but some survive

I'm not sure if I belong to this place.
I'm not sure if I want to stay my whole live here
I'm not sure if I should call this place "home"
Living here is not easy. But I think, there's no place where life is easy. I don't know why I'm bleating. I've got friends, my family. Well, I've got a broken family, but I accepted that I couldn't change this situation. I miss something. And I have to find out what it is. I don't know where I should start searching. Will I find it out? I don't know. I have to travel the whole wide world to find what's missing in my life. I know, there are a lot of things which went wrong but I know that I can't go back, it's all in the past. I think I became numb. I don't care about the things which are happening around me anymore. Why? What happened that I feel like this? I don't know. I will try to change it. I will try to be a better me, from now on. I'm sorry, I didn't mean to do you wrong.
I know I have to find what's missing. Will you help me?
