I feel like I’m abusing Gods grace and I’m so lost on how to continue

Hello everyone I am a recent inquirer into Orthodoxy Ive been attended my local parish and it’s been one of the best choices of my life but recently I’ve been dealing with the passion of lust which is not new as many young men deal with it but in the last couple weeks I relapsed into this addiction (idk if I’m allowed to say it but it has to do with adult content) and this has happened before but now I can’t even go a day without watching those things and it eats at me I am scared of becoming that old man and I am back in that loop of repentance and sin where I say I want to change but then I go right back to my own vomit like a dog I’ve been telling my priest about this and he’s been very helpful but if anyone has any advice on how I can get out of this circumstance I’d very much appreciate it i want to live a life of honoring God but I am too pathetic to even beat this and don’t even know how to ask for Gods help without it feeling fake I continue to pray for mercy but then I throw it away for moments of pleasure that lead me to feeling empty any advice would help God Bless
