A big problem with the discussion around mental health issues is the idea that your thoughts are a part of what you are, and somehow it is OK even if these thoughts become a problem for you. It turns out that what appear for us as thoughts are just complex chemical reactions occurring in our brain. You can definitely change this chemistry using substances (for the better and for the worse). The same thing also works the other way around: uncomfortable, stressful thoughts can lead to chemical imbalances in the brain, because they're just the same thing. We need to better accept this fundamental fact of science and use it in our favor, not fight against this as if we depended on our mental moods to exist as an individual.
