Depression is a numbness, we don't give a fuck about anything or anyone.
Depression is a sadness but not just sadness, Anxiety, panic, thoughts of killing yourself well no one is home because you can't take the pain of your own emotions.
Depression is when you say "I wanna die." In your head over and over again until you break and selfharm with the dull pencil sharpener you keep in a tiny container by your bed. You don't want anyone to know how FUCKED UP YOUR MIND IS BECAUSE THEY WILL LEAVE LIKE EVERYONE ELSE. You hide these scars the resemble your sadness; not only your sadness your fear.
DEPRESSION IS NOT JUST SADNESS.
