Please, start studying carefully what's happening in your mind > https://oceanrecoverycentre.com/2016/07/the-ultimate-guide-to-overcoming-internet-porn-addiction/

First time without porn will be stressful , but if you resist , in some months you will feel reborn.

If the first times a person relapse easly, it's okay.
The streaks becomes even longer , day by day.
Don't porn anymore, it's better to struggle and at the last to relapse than to look at porn.
No more instagram pictures of models. No more erotic imagines , erotic stories or erotic asmr.
If you experience ''flatline'' and low libido , resist.

Replace the old habit with a new one , like read at bed and put away every electronic devices

 

The way porn works is that it is an addiction. Please don't take this as a bad thing though or think you are cursed though; it is ok, you can overcome this, and in this day and age, almost everyone is addicted, even if they don't realize it. But given by your description, seems like you are in the early stage, so be grateful that you can pull yourself out before it got worst.
