I masturbated again

During 6:00 or so, I got really horny and decided search up some stuff, I've been holding it in for about a week now. I've been getting these horrible intrusive thoughts about like if I masturbated again, satan will attack me. I know that the devil cannot touch me but I relapsed and now I am really scared, I need some advice and therapy, I never wanna do it again. God bless you all.
