Iiot masturbate daily 2 - 3 times

Hey guy's! i'm 26 years old, i've been masturbating since the age of 12 i guess, i tried to quit it many times, but everytime i fail, the best recrord i could make is 30 days challenge, my life started to get better, than i started doing it again, after that i started to do a lot of things, like not staying alone, i go camping in the weekends, i work 5 days, but the second i still do it daily 2 to 3 times. it's killing me, i'm so addicted to it, last day i had to do it at work, i'm so sick of it. i want to quit it so badly, is it normal ? what should i do ? any suggestions?
