Need Motivation

I have a problem close to yours but with a model I always search for her. I posted a thread about my decisions

So you should block her, then convince your brain you kicked her out of your mind. You should say to your brain : "I have forgotten her. I will not ever remember her name. I will not miss her because I have already forgotten her name!".
She is similar to a pornstar and you should forget anything related to porn. Only think about your new life and work hard for it. Learn new skills. Read books and study (This helped me so much in these 3 days I spent without remembering the model after I decided my decisions). Workout in the home because of the quarantine and install a program for working out. Eat healthy to gain muscles after exercising. You have many things you can do but stay away from your bed. Your bed is a trigger and makes you lazy, so use it when you sleep only.
Good luck bro. The key is making decisions. Don't be as you were before relapsing. You should make strict decisions like "I will not ever chat to her again. I don't know her name!!!. My brain is rebooting, so I shouldn't see anything like porn. I have a self control". It's my day 4 without PMOing. I feel happy. Insha'Allah we will succeed on NoFap. Remember the key is deciding and controlling your brain.

 

Forget your period of life you had with porn or with this girl. Treat with yourself as you are a new person who doesn't know what porn is and doesn't know girls send nudes. Treat with yourself as a clean person that doesn't fap and doesn't let his brain control him. This will help you absolutely but put on your mind that You can't break the rules! You should know that fapping gives you a pleasure for only seconds and then a pain, but controlling your urges for seconds or minutes everyday gives you a pleasure for your whole life.
