porn has completely destroyed me

I have completed stopped feeling attraction towards real women because of porn. I end up relapsing every other day to test myself to see if i can still get erections. Watching naked women in movies/tv shows doesn't get me hard anymore either.i end up relapsing every other day to see if i can still get erections and i have to physically stimulate myself while watching porn for a few good minutes to get any erection at all. Not to mention imagination doesn't get me hard either. I need guidance from you guys here.
