Get the hell out of your house and get running or working out. Put some battle music on to fire it up. Remove from the environment you feel to relapse.
Or keep taking cold showers. More than one cannot hurt.
I Relapsed just yesterday. I know exactly what you are going through and wish I’d just had more presence of mind. Just remember bro, you are not this kind of person who would do this stuff. Ok? It’s just not natural for you. You don’t even remember fapping after 34 days of awesomeness. Get that into your head. It’s just not worth it to even think about it.
Hope you get through. Do reply back after you’ve beat this.
