I feel nothing in me

Asking yourself what type of person and a man you want to be is a good start. Create a vision of yourself, if you do not have a solid reasons why are you doing NoFap you will have a hard time going through a painful process of cravings and urges.

In order for you to be a man that you admire, you need to find ways how to deal with painful struggles that will forge you into a man that you want to become. Most of pmo addicts here, including myself use porn to deal with our emotions. Its a way we deal with all types of emotions, since we have conditioned ourselves with porn to be our only tool to use when we feel happy, sad, tired, anxious, lonely ..we know nothing else, and its no wonder we feel like shit once we do NoFap and these emotions crawl back, since rule is not to use porn, what else are we left with ?

This is very crucial part, to feel like a man you want to be, and to become a man you want to be you need to learn how to be in control of your emotions and desires and learn how to manipulate them so they don't manipulate you. And that is through constant learning in this NoFap recovery.

Once you find and figure out the ways to deal with specific type of emotions, thoughts and desires through recovery, you will slowly but surely grow as a person and as a man. Learning such things, makes you get to know yourself, and that leaves you with major benefits in conquering everything else in your life, and then you will become a man you admire.

And best of all, when you pass through all of the struggle, you're constantly rewarded with benefits that NoFap brings. It is possible, but its not easy. Good thing is you're not the only one, and you have whole NoFap community to help you out.
Cheers.
