Hi Anthro- thanks for your post and sharing regarding your depression. I fully agree with everything you say- I too, suffered a nervous breakdown, and have ongoing anxiety and depression. I have found people generally understanding, or ignorant.
If you are explaining the illness to your family, I gave them a book called "Living with a Black Dog" which is a light-hearted take on depression but also makes clear that telling someone with depression to "cheer up" or "chin up" is not going to help at all.
I found that facing the illness head-on helped, but do not share it with others, except on a need-to-know basis. My family know, my close friends know, and my employer knows, and that's it. The stigma is definitely there, but it's getting better.
I also have alcoholism, the stigma from that is much more pronounced but again, the general reaction from others is not unkind- it's generally either understanding, or ignorance.
Accepting to yourself that you have an illness, which is just as real an illness as having a broken leg or diabetes, is a big first step.
Also, make sure the stigma isn't just in your own mind- we often suffer from self-consciousness and second-guess what others are thinking. We are often our own harshest critics, and if we do share that we have a mental illness, such as depression, my experience is you will be surprised at the responses, one of which very often is "I would never have known" and another is "I suffer too" or have a loved one that suffers.
Very best wishes x
