Depression is complex, in that everyone deals with it differently and everyone has their own feelings towards their depression. When people find out that I suffer from depression they are confused. "You seem so happy." "I never see you crying." "You're overreacting."
To those people with that reaction, I walk away. Because I smile everyday means I can't be depressed. Because I laugh and have a social life means I can't be depressed. Depression is not sadness, those words are not synonymous. I would be lying if I said I never get sad because I do. But that is not what depression is.
I have struggled to try to explain it to people who do not understand. To me, it feels like I'm drowning. It feels like gravity is crushing me and I can't move. It feels like I can feel the world spinning around me and I'm stuck in one place, and can't move.
"You're overreacting."
Never say this to a person with a mental health issue. You are overgeneralizing depression with that comment. There are times when I will not leave my bed for three days straight, not because I don't want to, but because I don't have the will or the drive to.
"I never see you crying."
Because I am not constantly sobbing does not mean I am not fighting my own mental battles. Faking a smile and pretending everything is Ok is a coping mechanism, one that helps a person with depression deal with daily life.
"You seem so happy."
Because I am happy, I am perfectly happy and content with my life at the moment, but that does not mean my mind thinks the same. My mind tricks me into believing in a hopeless future, one that is out of my control.
The biggest struggle I have faced with my depression is telling loved ones. They do not understand the feeling of being in that dark place with no ladder to climb out of it. And every day that they don't understand, it seems that place gets deeper and deeper. You feel the need to justify your actions or your mood swings or your trouble concentrating.
Everyone deals with depression differently, whether it be alone, with loved ones, taking medication, seeing a therapist, or any other means of help. But having depression is a force that makes you want to crawl into a hole and never come out.
