I had dropped out of a masters program because of depression in 2015. I free-lanced for a few years, co-founded a tech. startup and my depression diminished, but then I met with an accident in 2017 which gave me chronic back pain. Bed-ridden for months, I converted my full-time work to part-time, and also started working on my Masters thesis. I defended it successfully a few months back (i.e., in 2019). My back pain also has now decreased significantly. As an aside, my back pain was found to have a correlation with my mental health. It started alleviating after I stopped all medication and started living a normal life, with regular exercise routine.
Now, I wish to go back to academia and am applying for Masters/PhD programs. In my Statement-of-purpose, I would have to mention some reason for dropping out of my previous masters program, because it would be glaringly visible.
My question is: How ethical would it be to not mention my depression at all, and instead substitute it with my accident which caused the back pain? That is, if I mention that I met with the accident in 2015 instead of 2017, which caused me to drop out, would it be "right"?
I am thinking of this because as per this, this and this Academia.SE posts, sharing your depression (to your prospective supervisors) is usually not a good idea. And in my case, while the depression lingers beneath and raises its head once in a while, it is usually not present. So, if I am free of depression (but, definitely still "prone"), then should the history be mentioned?
