If you have been fapping since 13, then your brain has had a lot of stimulation and it is used to a dopamine high. As you abstain from PMO your brain will rewire.

Stick with this forum. There is a lot of wisdom and good will to help you.
Educate yourself with the articles here on porn and what it does to your brain and body.
Put a pron filter on your devices.
Develop alternate activities from porn. SOmething you like to do that will benefit your life. Many men increase their exercise leve.
To help with urges, learn to deep breath and to watch as the urge subsids (which it will if you let it)
Seek out a friend who will support and encourage you in your efforts.
Resolve to learn from any failures you may have along the road. Do not try to become stronger by berating yourself. This doesn't work. Yes, get angry at what has been stolen from your life, but that is not YOU. You are gaining in strength and wisdom. Appreciate that.
