There is no way to detect true myopia and pseudomyopia at home. If you want to distinguish between true myopia and pseudomyopia, you must go to a regular hospital for a pupil dilatation and optometry test to find out if you have true myopia or pseudomyopia. This is the way to distinguish between true myopia and pseudo-myopia. Pseudomyopia can gradually return to normal after reasonable eye habits, while true myopia has no way to return to normal again.
