I'm not on tumblr so couldn't reblog directly, but I found this via Geeky Therapist
From the original post:
This is the greatest thing I have ever seen. People do not understand that mental illnesses, such as depression, are actual chemical imbalances in your body. They are not brought on by choice. My dad was diagnosed with depression. He was so ashamed of it that he hid it from me and my brothers. A month later, he killed himself. The stigma that comes with mental illness made my Dad embarrassed to talk to his own kids about this problem because he felt like less of a man.
Erase the stigma. The more we talk about mental illness, the less likely it will end in suicide.
Pass it on.
