A Humble Request for Guidance on the Path to Becoming a Better Muslim

As-salamu alaykum, I'm reaching out in hopes of finding some guidance on how to strengthen my faith and become a better Muslim. Alhamdu lillah, I've been blessed with the opportunity to perform Umrah twice in the past year, and I've witnessed firsthand the blessings of Allah in my life. However, after each Umrah, I've found myself slipping back into old habits that are not pleasing to Allah, and it's left me feeling lost and disconnected from my faith. Recently, I lost my job, but Allah's mercy and wisdom are beyond my understanding, and I was able to perform my second Umrah soon after. I've started making changes, like praying more consistently, performing Tahajjud, and fasting voluntarily, but I'm struggling with the weight of my past sins and the fear of death and the afterlife. I'm trying to repent and give charity as much as I can, even without a steady income, especially during this blessed month of Ramadan. I'd love some advice on how to stay consistent with my prayers, recite the Quran in Arabic again, and trust in Allah's plan for me. I know that having faith in Allah is the most important thing, and praying regularly has helped me overcome some of my struggles, but I'm scared of relapsing and not fulfilling my promises to Allah. This worldly life can be such a test, but I'm hoping to find my way and make amends. Insha'Allah, I pray that all Muslims around the world enter Jannah and receive a good ending in this life. Jazakum Allahu khayran to whoever takes the time to read this and offer guidance.
