Want to get back on track and feel more connected with Allah

I've been feeling really disconnected from Allah lately. For the past month I've been trying to get closer to Him, but after 2-3 days I end up falling into some sin again. When I pray, I don't feel that spiritual connection I used to have before. I really want to rebuild my relationship with Allah and develop a meaningful connection. Coming from a family with many cultural traditions that aren't actually Islamic makes me feel like everything is so difficult and that I'll be punished. I need advice on how to pray properly, maintain daily zikr, and read Quran regularly. To be completely honest, when Ramadan started I decided to leave certain sins behind, but after a week I fell back into them. Can anyone explain why this keeps happening? When I see Islamic motivational content, I feel inspired at night, but the next morning I struggle to pray. Prayer has become more of a daily obligation than a spiritual connection for me. I really need serious guidance. Another issue is my friend group - they're not good influences honestly, but without them I feel alone. I tried distancing myself for two months, but at school I end up slipping into sins with them like backbiting, inappropriate thoughts, and bad language. They vape and do other things, and I even tried it briefly a couple times. It's surprisingly addictive, but I stopped quickly. I hope someone can take time to advise me on how to fix my life and return to the right path. InshaAllah
