that would result in fewer returning customers for the pharmaceutical industry
If I can add, psychology seems to have become an industry as well. I am Canadian and technically have access to free healthcare. However, like in many other countries, the resources are so overwhelmed that many are unable to access any form of treatment because they cannot afford private care. I have always been told medication alone cannot help and you should always do some form of therapy if you are taking it.
If we had a cure for depression and other mental health illnesses, I think psychologists would also try to stop it from reaching the markets. Being in the same situation as you as a long time sufferer with little options to stop it, I do hope that either something will change soon or that at least, for those after us.
I have started to knit. I usually will watch TV or listen to a podcast and as I become better, I try more complex projects that force me to put more thought in what I'm doing.
I started out not doing anything specific, basically different lengths of squares and rectangles, because I also struggle with motivation to do anything. It was really just so I would have something to do and keep myself busy with. Then I started to include more simple techniques and then motifs and now patterns. If it's something that interests you, I think it's a great way to get distracted and at the end of it, you get a "reward" (being whatever you knit).
I hope you find something that helps you and that eventually you overcome depression.
