Can a journal article contain a personal circumstance description as motive for justifying the literature approach?
If you submit the article to a peer-reviewed journal, the reviewers should not (be able to) look at your academic history or status. If it gets accepted, the fact that it has been accepted shows that people think the findings are relevant for the field. There is no need to defend yourself in the text.

Furthermore, I would avoid any personal statements, especially if it concerns your own mental health, as it may jeopardise your career in the future.
