Any advice would be amazing

I am honestly wanting to know how people really have overcome porn and masturbation addictions . I haven't been able to overcome either of mine , the longest I've gone without either was probably 4 days and that's a real push . Today I watched porn and fapped twice which I've never done I feel like it's getting worse for me . I've tried so many things over these past years. But nothing has ever worked for me. And even if I go a day or two I get the worst urges like I have to stop everything I do and try and ignore them. I really don't want to ask anyone close to me as I find it embarrassing.

I really want to stop both

In the end what helped you guys to overcome these addictions?

Any advice would be so greatly appreciated

Thank you very much
