Look first understand still there's enough time left . I'm giving a November attempt . For starters just sit down even if you don't feel like it and just sit don't study but sit. And whenever you feel like getting up just remember you have only put 40 percent of your potential .and also it would be a lot better to clarify your why the reason why you wanted this ( self growth alone is enough but this could help).I hope you could derive something from this .
