How can I break this cycle? I feel like my own worst enemy.

Sometimes I think my nafs gets the best of me, and I become my own ungrateful worst enemy. I just needed to let this out, so here goes. Alhumdulillah, I'm Muslim, but I fall short in showing gratitude and respect for some of the biggest gifts Allah gives believers-like time, opportunities in this dunya, intellect, and His guidance. It feels like I keep asking Allah for chances, and when He grants them, I get careless and don't value them like I should. I put off the things that matter every single day. Maybe I do try, but it's never enough because I end up right back in the same mess, just tangled up in my problems again. I'm ungrateful because I forget what I even asked for in my duas once it's given. I start feeling like I don't deserve to ask for anything anymore. I'm not even good for myself. I swear every time that I won't repeat the same habits, but I do, and I'm so tired. Still, I'll try one last time, shamelessly turning to Allah and asking again.
