In hell

you are not alone, there's a person inside you who knows that you are on a wrong path. Keep your eyes closed for a minute and listen to that person. He is your well wisher, he is saying you to not touch your organ. He is saying you to not watch P. He may not be able to tell you what to do instead, because of the chemicals in your brain that has created a fog. Now that well wisher is none but you yourself your conscience. Just understand that it is not YOU who wants to fap its just the chemicals inside your brain. So don't blame yourself. Just feel those chemicals but DON'T Act on them. Since you are alone so the challenging thing is how to divert your mind. I don't know about your time zone, if its day time or evening you can just lock your house and go outside enjoy the nature. If its not possible do 100 pushups or some exercise. Or simply Dance on a song or do something which makes your body Active. Avoid passive things like Reading, or something in which your body is not active. DO some Action stuff for like 1-2 hours than later on make strategy as per your mood. All The Best fighter !
