Struggling after a blessed journey to Umrah

Last year, my family and I had the opportunity to go for Umrah, which my mother really pushed for because of my struggle with smoking. I've been hooked since I was young, and she's caught me too many times. It's something I feel deep shame about, but I keep going back after promising to quit-vapes and cannabis keep tempting me. I hide it until I get too comfortable and slip up. During Umrah, I found such peace. Being away from daily life and surrounded by my family curbed all my cravings. The unity and love of the Ummah filled me with hope, and my heart felt calm, like it did when I was a kid. Even though I'd stayed clean for months, I relapsed recently, and my mother found out. She hasn't said anything, and I'm not sure if I should approach her first. I feel like her arranging Umrah was her last big effort, so I worry she might have lost hope in me. Still, despite my mistakes, I pray regularly and remind my younger siblings to stay close to their deen. I don't want to lose my bond with my mother, and I know I need to make it right. Insha'Allah, I'm planning to go for Umrah again this year with a sincere intention. Anyone dealt with this and have advice on how to talk to your mom?
