Seeking Guidance: How Can I Get My Life Back on Track?

As-salamu alaykum, brothers and sisters. Around three years ago, I was doing really well-top of my class, studying computer science at a respected university, with good grades and a bright future ahead. I even got a great internship and thought everything was set. But then, I started getting too comfortable, hanging out with the wrong crowd, wasting time watching movies, and spending hours online playing games. Slowly, I lost control. I tried to quit many times-deleted apps, cancelled subscriptions-but something else would always distract me, whether it was YouTube, Instagram, or games. I can't focus or stay consistent anymore, and I feel like I'm losing myself. Because of this, my grades dropped badly last year, and I missed out on a return job offer. Now, I have an average job that pays okay, but I feel like I'm wasting my life. My sleep schedule is messed up-I wake up late, skip meals, feel tired all day, and my productivity is low. Even when I wake up early, I find myself scrolling through my phone for hours, and often end up late for work because of it. My wife has been by my side for three years, and she's amazing-smart, supportive, and ambitious. She’s tried to help me change, but I keep falling back into bad habits. Lately, she’s grown distant, and I understand why. She deserves better than the person I’ve become. She’s the best thing in my life, and last year she really tried to support me, but I went back to my old ways. In the past few months, she’s started focusing more on herself and has been giving me less attention. I used to be disciplined, fit, and confident, but now I’ve lost my focus, health, and direction. I know I’m slipping, and I’m scared of losing everything-my job, my marriage, and myself. How can I rebuild my life from here? How do I stop being careless, lazy, and caught up in distractions, and become the person I once was? Jazakum Allahu khairan for your advice.
