If there's nothing you can do to change this feeling I understand that but try to look the bright side even if 80% of it is dark.Being depressed is more dangerous than any kind of addiction it drains your brain ability to handle yourself and when you get deep into this sadness nothing will make you happy or satisfied cause of Ur brain already adapted the emptiness which is gonna affect your entire life,so you need accept Ur self and try to stabliize yourself there's nothing u'll get from depress
