Astrid Lee Miles said this quote

No. Depression is the unseen, unheard, silent killer. It is the pain that is too much to cope with, too hard to deal with and never understood. It is something that you can’t escape, no matter how hard you try it ALWAYS swallows you again. It constantly follows you around, like black smoke choking you from the inside out. Like a lion clawing at your heart and mind, eating pieces of you until there is nothing left.
