Hi Krish, So you have been over masturbating, an now you want to get well, yes?
For now you need to take a break from masturbating or any sexual contact, and if you watch porn that needs to go as well, its an 8 week break you need, this will give your body a chance to reboot.
But please keep this in mind, its taken you 12 years to get to this point, so there is no quick way back, your body needs to heal and it will if you give it this chance.
