Relapsed after 12 days

I’ve been on a NoFap streak for 12 days and just now i broke it and relapsed. I knew it was gonna happen to me i couldn’t stop myself in time. I’m disappointed in myself because i did so good. I got super high last night so i think that’s what caused me to relapsed because every-time i get high it makes me super horny and i just touch myself. Im restarting now as we speak and imma go back better and stronger.
