I have not been getting along with my family recently, and they do not get what I am going through with stress from school and home. My girlfriend lives 20 hours away, and I just couldn't take it anymore, so I ran away,and I am only 17. My parents went after me and took me back, but for the short time I was with her, I had never been more happier in my life... Now when I am back home everything feels different... Like I don't belong, like this is all just a dream. It seems unreal to me. I no longer can remember anything, and I never no what I am doing, it's like I can't even control myself. I can hardly feel pain anymore too, and also I no longer can focus, even on the smallest of things... The only time now when things feel right and normal is when I'm talking to my girlfriend... I no longer am happy at all unless I am with her, what can this be? Depression ?
