Feeling Overwhelmed and Seeking a Stronger Connection

Assalamu alaikum. I've been going through a tough time lately, feeling really down on myself. It's like I've been letting my days slip away without appreciating them, and it's starting to weigh heavily on my mind. I've always identified as a Muslim, but I've never really dived deeply into my faith, and I truly want to change that. This past Ramadan, I managed to fast, but I struggled with praying and I only got through an English translation of the Quran once. I know I should be doing more, but I'm not sure where to even begin. Time just seems to be flying by, and I find myself constantly worrying about what comes after this life. Some nights, I get scared-what if Jannah isn't real? What if death is just the end? My heart pulls me towards belief in the hereafter, but my mind sometimes fights it, as if it's just a way to cope with the unknown. I'm especially anxious that my mistakes and my current lack of strong faith might have consequences. I also really struggle with controlling my anger and my thoughts, and I feel like these things are putting a distance between me and Allah. If anyone has been in a similar place or has advice on how I can not only address these issues but also grow into a person with stronger, more sincere faith, I would be so incredibly grateful. Jazakallah khair to anyone who takes the time to read this and offer some guidance.
