First of all, I would like to state that there is no relation between stress and Retinal Tears. Secondly, from your history, it is apparent that you do not have central serous retinopathy. Also, SR has no relation with retinal tears either. Retinal tears develop spontaneously in individuals with myopia due to traction on the peripheral retina by the vitreous jelly within the eye and associated weak spots in the retina prone to develop tears.
Next, I would like to state that cells below the retina may leak out through the tear and precipitate a chain of chemical events which can cause a membrane formation on the retinal surface, which is known as an epiretinal membrane on the central area of the retina or macula. If that is the diagnosis in your case, you will need regular retina checks for the next few years.
