Salam alaykyum I want help will my dua and prayers be accepted though I masturbate and repent and masturbate and repent I want the answer yes or no

My name is Leo (fake name) I'm 17 I keep masturbating through I promised Allah not to do it but I done it and I feel sad and scared. I always ask Allah the same dua. But I'm scared that it won't be accepted because I masturbate. Please can someone help me stop and answer if masturbating will make my duas and prayers not accepted
