I wouldn’t be afraid of your failures, rather see them as mountains you need to accomplish. If you wish you loved God more, pray for the strength too.

If you fall to temptation never give up! Thats what the devil wants, keep on trying! I have overcome sin in my life that keeps on coming back to try to haunt me, and it has literally taken me months to get to the point that I am at.
I recommend praying daily for strength, and the ability to give your life to God. If you wish you had some strength that you don’t have pray for it. Sin is a uphill battle and God understands. So don’t give up when you falter! Padre Pio said when you commit sin, say an act of contrition and go to the next possible confession. He said not to worry; its what the devil wants.
I wouldn’t worry about your failures, just focus on where you want to be in your relationship with God. Let his warmth take and guide you closer to him, through prayer and devotion
I also recommend getting a scapular and wearing it 24/7 (I take mine off for showers though to preserve it), I also recommend about reading the lives of Saints that have to deal with your specific temptations, and asking for their intercession. Also pray the Rosary daily. I some times go to sleep holding one if I am being tempted so you could try that too if you think it would help
I hope I’ve been helpful, and just know that through God, anything is possible
