If you are suffering from depression, chronic or otherwise, first, I am sorry to hear that. It is a difficult place to be. I wish I knew of a technique that worked for everyone but unfortunately I do not.
I recently recovered from a long bout with depression myself. I'm not entirely certain what caused the difference after so many years. One potential thing is that I went through an experience that reset my gut bacteria. It sounds a little strange that that might be the thing, but it seems to be the most logical explanation.
I don't know if it will work for others, but I'm putting it out there in case it does.
So the people responding the advice can still be helpful aren’t actually responding to the many people including me with issues with the post.
