How many people have asked that question? I have asked it from the time I learned I had depression. I pray that it is not because I do not want my children to develop it.
I did some research on the internet and wrote a blog on this subject matter. I discovered that genetics do play a part in depression but there are many other factors that play a role too. Go to my blog to learn about all the other factors and to learn whether depression is genetic or not.
Please feel free to poke around my blog and refer me for google search or become a follower of my blog.
